XC6222 Series
700mA High Speed LDO Regulator with Reverse Current Protection
■GENERAL DESCRIPTION
The XC6222 series is a highly accurate, low noise, high ripple rejection, low dropout, and low power consumption high speed
CMOS voltage regulator. The series consists of a voltage reference, an error amplifier, a driver transistor, a current limiter, a
thermal protection circuit, a reverse current protection circuit and a phase compensation circuit.
The CE function enables the entire circuit to be placed in a stand-by state by inputting a low level signal to the CE pin. In this
stand-by mode, the electric charge at the output capacitor (CL) will be discharged by the internal auto-discharge switch, and as
a result the VOUT pin will quickly return to the VSS level.
Over-current protection and thermal protection circuits are integrated. The protection circuit starts to operate when either output
current reaches the current limit level or junction temperature reaches the temperature limit. With the reverse current
protection function, the reverse current flow is prohibited when VOUT voltage is higher than VIN voltage.
The protection diode of IC is not necessary.

NOTE:
* 1: Unless otherwise stated, input voltage is VIN=VOUT(T)＋1.0V.
* 2: VOUT (E) is effective output voltage (Refer to the voltage chart E-0 and E-1)
It is defined as output voltages when an amply stabilized VOUT (T) ＋1.0V is supplied to the VIN pin while maintaining a certain
IOUT .
* 3: The relation between VOU T (E) and VOUT (T) is shown in the voltage chart E-0 and E-1.
* 4: VOUT (T) is nominal output voltage
* 5: Vdif = {VIN1(*7)-VOUT1(*6)}
* 6: VOUT1 equals 98% of the output voltage when amply stabilized VOUT (T) +1.0V are supplied to the VIN pin.
* 7: VIN1 is the input voltage when VOUT1 appears at the VOUT pin while input voltage is gradually decreased.
* 8: Reverse current (IREV) flows from VOUT to VIN.
* 9: VOUT pin sink current (IREVS) flows from VOUT to VSS.
*10: For the XC6222A/C series only. In the XC6222B/D series, the current flows from the VOUT pin to the VSS pin via the internal switch
when CE pin is low. Please do not connect another power supply to the VOUT pin. Please also note when the XC6222A/C series
connects external power supply to the VOUT pin, please use it within the range from VOUT(E) (actual output voltage value)or more to
6.0V or less. When the voltage less than VOUT(E) is applied to the VOUT pin by adding a power supply or battery, a low level signal
should be input to the CE pin for chip disable in order to protect a reverse current at VIN < VOUT.
*11: For the XC6222B/D series only. The XC6222A/C series discharges via two resistors R1 and R2 shown in the block diagram.

■OUTPUT VOLTAGE CHART (Continued)
●Voltage Chart 2
8/26
XC6222 Series
■OPERATIONAL EXPLANATION
The voltage divided by two resistors R1 and R2 is compared with the internal reference voltage by the error amplifier. The
P-channel MOSFET connected to the VOUT pin, is then driven by the subsequent output signal. The output voltage at the VOUT
pin is controlled and stabilized by a system of negative feedback. The current limit and short protection operate in relation to
the level of output current. The thermal protection operates in relation to the level of heat generation. The reverse current
protection operates when VOUT voltage is higher than VIN voltage. Further, the IC's internal circuitry can be turned off via the CE
pin's signal.
<Input and Output Capacitors>
The XC6222 needs an output capacitor CL for phase compensation. Values required for the phase compensation are shown in
the chart below. If a loss of the capacitance happens, stable phase compensation may not be obtained. Please ensure to
use a capacitor which does not depend on bias or temperature too much. For a stable power input, please connect an input
capacitor CIN of 1.0μF between the VIN pin and the VSS pin.
OUTPUT VOLTAGE (V) OUTPUT CAPACITOR VALUE
0.8V～2.05V CL=6.8μF (MIN.)
2.1V～2.45V CL=4.7μF (MIN.)
2.5V～5.0V CL=2.2μF (MIN.)
<Reverse Current Protection>
The XC6222 series includes reverse current protection to prevent the damage to any connected products such as batteries as a
result of current flow from the VOUT pin to the VIN pin. When VIN is smaller than VOUT, the reverse current protection works and
suppress the reverse current to 1.5μA (MAX.). When VIN is smaller then VOUT, the VOUT pin sink current flows from the VOUT
pin to the VSS pin is 95μA (TYP.) as the IC operation current. With the XC6222A/C series, when a low level signal is inputted
to the CE pin, the sink current of the VOUT pin is minimized to 2.8μA (TYP.). However, with the XC6222B/D series, when a low
level signal is inputted to the CE pin, the sink current of the VOUT pin goes through the CL auto discharge circuit to the VSS pin
which may result in the IC being damaged. In this case, please do not connect a power supply to the VOUT pin.
Please also note when the XC6222A/C series connects external power supply to the VOUT pin, please use it within the range
from VOUT(E) (actual output voltage value)or more to 6.0V or less. When the voltage less than VOUT(E) is applied to the VOUT pin by
adding a power supply or battery, a low level signal should be input to the CE pin for chip disable in order to protect a reverse
current at VIN < VOUT.
Example) The voltage less than VOUT(E) (actual output voltage value) is applied to the VOUT pin as "OR" connection.

* When the CE pin is connected to the VIN pin, an output voltage 2.8V
from the step-up DC/DC goes through to the VIN pin as reverse
current up to around 150mA if the USB connection is removed from
the VIN pin (VIN < VOUT). CE pin voltage should be maintained low
when the USB connection is removed from the VIN pin.

XC6222
Series
<Current Limiter, Short-Circuit Protection>
The XC6222 series’ fold-back circuit operates as an output current limiter and a short protection circuit for the output pin.
When the load current reaches the current limit level, the fixed current limiter circuit operates and output voltage drops. When
the output pin is short-circuited to the VSS pin, the current is decreased to a level of 55mA.
<Thermal Shutdown>
When the junction temperature of the built-in driver transistor reaches the temperature limit level (150℃ TYP.), the thermal
shutdown circuit operates and the driver transistor will be turned OFF. The IC resumes its operation when the thermal
shutdown function is released and the IC’s operation is automatically restored because the junction temperature drops to the
level of 125℃ (TYP.) as the thermal shutdown release voltage.
■OPERATIONAL EXPLANATION (Continued)
<CL Auto-Discharge Function>
XC6222B/D series can discharge the electric charge stored in the output capacitor (CL), when a low signal to the CE pin, which
enables the whole IC circuit to be turned off, is inputted via the N-channel transistor located between the VOUT pin and the VSS
pin (cf. BLOCK DIAGRAM). The CL auto-discharge resistance value is set at 530Ω(TYP.). The discharge time of the output
capacitor (CL) is set by the CL auto-discharge resistance (R) and the output capacitor (CL). By setting the time constant of the
CL auto-discharge resistance value [RDCHG] and the output capacitor value (CL) as τ(τ=C x RDCHG), the output voltage after
discharge via the N-channel transistor is calculated by the following formula.
V = VOUT(E) x e –t/
τ
, or t=
τ
In ( V / VOUT(E) )
where
V: Output voltage after discharge

OUT (E): Output voltage
t: Discharge time
τ: CL auto-discharge resistance RDCHG×Output capacitor (CL) value C)
<CE Pin>
The entire XC6222 circuitry can be turned off via the CE pin signal. In shutdown mode, output at the VOUT pin will be pulled
down to the VSS level via R1 & R2. However, with the XC6222B series, the CL auto-discharge resistor is connected in parallel to
R1 and R2 while the power supply is applied to the VIN pin. Therefore, time until the VOUT pin reaches the VSS level is shorter.
For the XC6222A/B series, the output voltage becomes unstable, when the CE pin is left open. If this CE pin voltage is set with
the specified voltage range, the logic is fixed and the IC will operate normally. However, the supply current may increase as a
result of shoot-through current in the IC's internal circuitry when a medium voltage is input to the CE pin. With the XC6222C/D
series, when the CE pin is left open, output voltage is fixed to VSS level.
■NOTES ON USE
1. Please use this IC within the stated absolute maximum ratings. The IC is liable to malfunction should the ratings be
exceeded.
2. Where wiring impedance is high, operations may become unstable due to noise and/or phase lag depending on
output current.
Please wire the input capacitor (CIN) and the output capacitor (CL) as close to the IC as possible.
