BCD Semiconductor Manufacturing Limited
150mA EXTREMELY LOW NOISE LDO REGULATOR AP2121
General Description
The AP2121 series are positive voltage regulator ICs
designed by CMOS process. Each of these ICs consists
of a voltage reference, an error amplifier, a resistor net-
work for setting output voltage, a current limit circuit
for current protection and a chip enable circuit (5-pin
products only).
The AP2121 series have features of high ripple rejec-
tion, low dropout voltage, low noise, high output volt-
age accuracy, and low current consumption which
make them ideal for use in various battery-powered
devices.
The AP2121 series have 1.5V, 2.5V and 3.2V versions.
The AP2121 are available in standard SOT-23-3 and
SOT-23-5 packages.
