ACE ACE515A28QM+H 300ma high speed, extremely low noise cmos ldo regulator Datasheet

ACE515A
Technology
300mA High Speed, Extremely Low Noise CMOS LDO Regulator
Description
ACE515A series are 300mA, positive voltage regulator ICs fabricated by CMOS process.
Each of these ICs is equipped with a voltage reference, an error amplifier, a resistor network for setting
output voltage, a chip enable circuit, a current limit circuit and OTSD (over temperature shut down) circuit
to prevent the IC from over current and over temperature.
The ACE515A series have features of high 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
apparatus.
The ACE515A have 1.8V, 2.5V, 2.8V, 3.0V, 3.3V, 4.15V and 4.2V fixed voltage versions.
These ICs are available in tiny SC-70-5 and SC-82 packages as well as industry standard SOT-23-3 and
SOT-23-5 packages.
