Ordering Information
General Description
The RT9011 is a dual channel, low noise, and low dropout
regulator sourcing up to 300mA at each channel. The range
of output voltage is from 1.2V to 3.6V by operating from
2.5V to 5.5V input.
The RT9011 offers 2% accuracy, extremely low dropout
voltage (240mV @ 300mA), and extremely low ground
current, only 27μA per LDO. The shutdown current is near
zero current which is suitable for battery-power devices.
Other features include current limiting, over temperature,
output short circuit protection.
The RT9011 is short circuit thermal folded back protected.
The IC lowers its OTP trip point from 165°C to 110°C when
output short circuit occurs (VOUT < 0.4V) providing
maximum safety to end users.
The RT9011 can operate stably with very small ceramic
output capacitors, reducing required board space and
component cost. The RT9011 is available in fixed output
voltages in the TSOT-23-6, WDFN-8L 2x2, WDFN-10L 3x3,
WDFN-8L 3x3 and WDFN-6L 1.6x1.6 packages.

Applications Information
Like any low-dropout regulator, the external capacitors used
with the RT9011 must be carefully selected for regulator
stability and performance. Using a capacitor whose value
is > 1μF on the RT9011 input and the amount of capacitance
can be increased without limit. The input capacitor must
be located a distance of not more than 0.5 inch from the
input pin of the IC and returned to a clean analog ground.
Any good quality ceramic or tantalum can be used for this
capacitor. The capacitor with larger value and lower ESR
(equivalent series resistance) provides better PSRR and
line-transient response.
The output capacitor must meet both requirements for
minimum amount of capacitance and ESR in all LDOs
application. The RT9011 is designed specifically to work
with low ESR ceramic output capacitor in space-saving
and performance consideration. Using a ceramic capacitor
whose value is at least 1μF with ESR is > 20mΩ on the
RT9011 output ensures stability. The RT9011 still works
well with output capacitor of other types due to the wide
stable ESR range. Figure 1. shows the curves of allowable
ESR range as a function of load current for various output
capacitor values. Output capacitor of larger capacitance
can reduce noise and improve load transient response,
stability, and PSRR. The output capacitor should be located
not more than 0.5 inch from the VOUT pin of the RT9011
and returned to a clean analog ground.

Thermal Considerations
Thermal protection limits power dissipation in RT9011.
When the operation junction temperature exceeds 170°C,
the OTP circuit starts the thermal shutdown function and
turns the pass element off. The pass element turns on
again after the junction temperature cools by 40°C.
RT9011 lowers its OTP trip level from 170°C to 110°C
when output short circuit occurs (VOUT < 0.4V) as shown
in Figure 2. It limits IC case temperature under 100°C and
provides maximum safety to customer while output short
circuit occurring.
For continuous operation, do not exceed absolute
maximum operation junction temperature 125°C. The
power dissipation definition in device is :
PD = (VIN-VOUT) x IOUT + VIN x IQ
The maximum power dissipation depends on the thermal
resistance of IC package, PCB layout, the rate of
surroundings airflow and temperature difference between
junction to ambient. The maximum power dissipation can
be calculated by following formula :
PD(MAX) = ( TJ(MAX) - TA ) /θJA
Where TJ(MAX) is the maximum operation junction
temperature, TA is the ambient temperature and the θJA is
the junction to ambient thermal resistance.

For recommended operating conditions specification of
RT9011, the maximum junction temperature is 125°C. The
junction to ambient thermal resistance ( θ
JA is layout
dependent ) for TSOT-23-6 is 220°C/W, WDFN-8L 2x2 is
165°C/W, WDFN-10L 3x3 is 108°C/W, WDFN-8L 3x3 is
108°C/W and WDFN-8L 1.6x1.6 is 175°C/W on the
standard JEDEC 51-3 single-layer thermal test board. The
maximum power dissipation at TA = 25°C can be calculated
by following formula :
PD(MAX) = ( 125°C 25°C ) / (220°C/W) = 0.455W for
TSOT-23-6 packages
PD(MAX) = ( 125°C 25°C ) / (165°C/W) = 0.606W for
WDFN-8L 2x2 packages
PD(MAX) = ( 125°C 25°C ) / (108°C/W) = 0.926W for
WDFN-10L 3x3 packages
PD(MAX) = ( 125°C 25°C ) / (108°C/W) = 0.926W for
WDFN-8L 3x3 packages
PD(MAX) = ( 125°C 25°C ) / (175°C/W) = 0.571W for
WDFN-6L 1.6x1.6 packages
The maximum power dissipation depends on operating
ambient temperature for fixed TJ(MAX) and thermal
resistance θJA. For RT9011 packages, the Figure 3 of de-
rating curves allows the designer to see the effect of rising
ambient temperature on the maximum power allowed.
