HIGH SPEED, EXTREMELY LOW NOISE LDO REGULATOR
General Description
Features
Data Sheet AP2121
The AP2121 series are positive
voltage regulator ICs fabricated by
CMOS process.
Each of these ICs consists of a
voltage reference, an error amplifier, a resistor network for setting output
voltage, a current limit circuit for current protection and a chip-enable circuit (5-pin products only).
The AP2121 series feature high supply
voltage ripple rejection, low dropout
voltage, low noise, high output
voltage accuracy, and low current consumption which make them ideal for use in various battery-powered devices.
