NJU7276
Low Dropout Voltage Regulator with Reset
GENERAL DISCRIPTION
The NJU7276 is a low drop out voltage regulator with
input-monitor reset function with internal fixed delay.
Advanced CMOS technology achieves ultra low current
consumption and high accuracy.
It delivers up to 5V/100mA output power with the maximum input
voltage of 9V.
The NJU7276 suitable for MPU applications.
