Data Sheet
General Description
The AP2126 series are positive voltage regulator ICs
fabricated by CMOS process.
The AP2126 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.
AP2126 is available in 1.25V to 5.5V adjustable
voltage versions.
AP2126 series are available in SOT-23-5 Package.
