AP2127
300mA HIGH SPEED, EXTREMELY LOW NOISE CMOS LDO REGULATOR
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 (for fixed versions only),
SOT-23-3 (for fixed versions only), SOT-23-5, SOT-89 (for fixed
versions only) and DFN-2x2-6 packages.
