HIGH SPEED, EXTREMELY LOW NOISE LDO REGULATOR AP2120

General Description

The AP2120 series are positive voltage regulator ICs
fabricated by CMOS process. Each of these ICs con­sists of a voltage reference, an error amplifier, a resis­tor network for setting output voltage, a current limit
circuit for current protection.

The AP2120 series feature high supply voltage ripple
rejection, low dropout voltage, low noise, high output
voltage accuracy, and low current consumption which
make them ideal for use in various battery-powered
devices.

The AP2120 series have 1.2V, 1.3V, 1.5V, 1.8V, 2.5V,

2.8V, 3.0V, 3.2V, 3.3V, 3.6V, 4.0V and 5.0V versions.

The AP2120 are available in standard SOT-23, SOT-89
and TO-92 packages.

Note 1: Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device.
These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated
under "Recommended Operating Conditions" is not implied. Exposure to "Absolute Maximum Ratings" for extended periods
may affect device reliability.
Note 2: Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifica­tions do not apply when operating the device outside of its operating ratings. The maximum allowable power dissipation is a
