300mA HIGH SPEED, EXTREMELY LOW NOISE CMOS LDO REGULATOR
General Description
Features
AP2126
The AP2126 is a 300mA, positive Voltage regulator
ICs fabricated by CMOS process.
Each of AP2126 is equipped with a voltage reference,
an error amplifier, a resistor network for setting output
www.DataSheet4U.vcoomltage, a chip enable circuit, a current limit circuit and
OSTD (over temperature shut down) circuit to prevent
the IC from over current and over temperature.
The AP2126 has features of high ripple rejection, low
dropout voltage, low noise, high output voltage
accuracy, and low current consumption which make it
ideal for use in various battery-powered apparatus.
AP2126 has 3.3V fixed voltage version. It is available
in SOT-23-5 Package.
