Data Sheet
General Description
The AP2127 Series are positive voltage regulator ICs
fabricated by CMOS process.
The AP2127 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.
AP2127 has 1.0V, 1.2V, 1.5V, 1.8V, 2.5V, 2.8V, 3.0V,
3.3V, 4.2V, 4.75V, 5.2V fixed voltage versions and
0.8V to 5.5V adjustable voltage versions.
AP2127 series are available in SOT-23-5 Package.
