NJU7272
Low Dropout Voltage Regulator with Reset
GENERAL DISCRIPTION
The NJU7272 is a low drop out voltage regulator with
input-monitor reset function with 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 NJU7272 suitable for MPU applications.
