BCD Semiconductor Manufacturing Limited
General Description
The AP2129 is a 300mA, positive Voltage regulator
ICs fabricated by CMOS process. The AP2129
provides two kinds of output voltage operation modes
for setting the output voltage. Fixed output voltage
mode senses the output voltage on VOUT, adjustable
output voltage mode needs two resistors as a voltage
divider
The AP2129 Series have features of low dropout
voltage, low noise, high output voltage accuracy, and
low current consumption which make them ideal for
use in various battery-powered devices.
AP2129 has 1.0V, 1.2V, 3.3V fixed voltage version and
0.8V to 4.5V adjustable voltage version.
AP2129 series are available in SOT-23-5 Package.
