NJM2830
LOW DROPOUT VOLTAGE REGULATOR
GENERAL DESCRIPTION
The NJM2830 is a 300mA output low dropout voltage regulator
with ON/OFF control.
Advanced Bipolar technology achieves low noise, high ripple
rejection and low quiescent current.
2.0V to 15.5V output voltage range, 1µF small decoupling
capacitor, built-in noise bypass capacitor make the NJM2830
suitable for various applications.
