 AP2125 300mA, HIGH SPEED, EXTREMELY LOW NOISE CMOS LDO REGULATOR

1、芯片描述：

The AP2125 series are 300mA, positive voltage regulator ICs fabricated by CMOS process. Each of these ICs is equipped with a voltage reference, an error amplifier, a resistor network for setting output voltage, a chip enable circuit, a current limit circuit and OTSD (over temperature shut down) circuit to prevent the IC from over current and over temperature. The AP2125 series have features of high ripple rejection, low dropout voltage, low noise, high output voltage accuracy and low current consumption which make them ideal for use in various batterypowered apparatus. The AP2125 have 1.8V, 2.5V, 2.8V, 3.0V, 3.3V, 4.15V and 4.2V fixed voltage versions.

These ICs are available in tiny SC-70-5 packages as well as industrystandard SOT-23-3 and SOT-23-5 packages（点击即可咨询芯片详细信息）.
