NJM7800 3-TERMINAL POSITIVE VOLTAGE REGULATOR GENERAL DESCRIPTION The NJM7800 series of monolithic 3-Terminal Positive Voltage Regulators is constructed using the New JRC Planar epitaxial process. These regulators employ internal current-limiting, thermal-shutdown and safe-area compensation making them essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current. They are intended as fixed voltage regulators in a wide range of applications including local (on card) regulation for elimination of distribution problems associated with single point regulation. In addition to use as fixed voltage regulators, these devices can be used with external components to obtain adjustable output voltages and currents.

Ripple Rejection Ver.2013-07-08 NJM7800 Input Capacitor CIN Input Capacitor CIN is required to prevent oscillation and reduce power supply ripple for applications when high power supply impedance or a long power supply line. Therefore, use the recommended CIN value (refer to conditions of ELECTRIC CHARACTERISTIC) or larger and should connect between GND and VIN as shortest path as possible to avoid the problem. Output Capacitor CO Output capacitor (CO) will be required for a phase compensation of the internal error amplifier. The capacitance and the equivalent series resistance (ESR) influence to stable operation of the regulator. Use of a smaller CO may cause excess output noise or oscillation of the regulator due to lack of the phase compensation. On the other hand, Use of a larger CO reduces output noise and ripple output, and also improves output transient response when rapid load change. Therefore, use the recommended CO value (refer to conditions of ELECTRIC CHARACTERISTIC) or larger and should connect between GND and VOUT as shortest path as possible for stable operation In addition, you should consider varied characteristics of capacitor (a frequency characteristic, a temperature characteristic, a DC bias characteristic and so on) and unevenness peculiar to a capacitor supplier enough. When selecting CO, recommend that have withstand voltage margin against output voltage and superior temperature characteristic though Ver.2013-07-08 -7- NJM7800 TYPICAL CHARACTERISTICS Output Voltage VO (V) NJM7805/15/24 Output Characteristics (Io=0.5A, Tj=25C) Input Voltage VIN (V) NJM7812 Dropout Characteristics (Tj=25C) Output Voltage VO (V) Output Voltage VO (V) NJM7805 Dropout Characteristics (Tj=25C) Input Voltage VIN (V) Input Voltage VIN (V) Output Voltage VO (V) NJM7805/15/24 Load Characteristics (Tj=25C) Output Current IO (A) -8- Ver.2013-07-08 NJM7800 TYPICAL CHARACTERISTICS Dropout Voltage VIN -VO (V) NJM7805/24 Quiescent Current vs. Input Voltage (Tj=25C,) Quiescent Current IQ (mA) Output Current IO (A) NJM7800 Series Short Circuit Output Current (Tj=25C, Heat Sink) Input Voltage VIN (V) Output Voltage VO (V) NJM7805/15/24 Output Voltage vs. Junction Temperature Junction Temperature Tj (C) Ripple Rejection RR (dB) NJM7805/15/24 Ripple Rejection vs. Frequency VIN = 10V (05) ein = 2VP-P 19V (12) 33V (24) Tj = 25C Frequency (Hz) Ver.2013-07-08 -9- NJM7800 TYPICAL CHARACTERISTICS Output Voltage VO (V) NJM7805 Output Voltage vs. Temperature Ambient Temperature Ta(C) Output Voltage VO (V) NJM7808 Output Voltage vs. Temperature Ambient Temperature Ta(C) [CAUTION] The specifications on this databook are only given for information , without any guarantee as regards either mistakes or omissions.
