AP2129
AP2129 is EXTREMELY LOW NOISE CMOS LDO REGULATOR manufactured by BCD.
Description
Features
The AP2129 is a 300m A, 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, 1.8V, 2.6V, 2.8V, 3.0V and 3.3V fixed voltage version and 0.8V to 4.5V adjustable voltage version.
The AP2129 series are available in DFN-1.5x2-6 (1.0V, 1.2V, 1.8V, 2.6V, 2.8V, 3.0V, 3.3V) and SOT-235 (1.0V, 1.2V, 3.3V, ADJ) packages.
