CM2830/CM2830A

300mA CMOS LDO

GENERAL DESCRIPTION

The CM2830/CM2830A family is a positive voltage linear

regulator developed utilizing CMOS technology featured low

quiescent current (30

A typ.), low dropout voltage, and high

output voltage accuracy. Built-in low on-resistance transistor

provides low dropout voltage and large output current. A

2.2

F or greater can be used as an output capacitor.

The SOT-23-3, SOT-23-5, and TO-92 miniaturized package

and the SOT-89 package are recommended for configuring

portable devices and large current application, respectively.

These robust devices are designed to prevent device failure

under the worst operation condition with both Thermal

Shutdown and Current Fold-back.

FEATURES

Very Low Dropout Voltage

Low Current Consumption: Typ. 30

A, Max. 35

Output Voltage: 1.5V, 1.8V, 1.9V, 2.0V, 2.2V, 2.5V, 2.7V,

2.8V, 2.9V, 3.0V, 3.3V, 3.5V, 3.6V, and 3.8V

High Accuracy Output Voltage: +/- 1.5%
