CM2730

300mA DUAL LOW NOISE CMOS LDO

GENERAL DESCRIPTION

FEATURES

The CM2730 dual LDO family are positive linear voltage

ꢀ

Very Low Shutdown Current < 2.0µA

Very Low Dropout Voltage: 300mV @ 300mA

Low Current Consumption: Typ. 60µA, Max. 70µA

Output Voltage: master LDO1 fixed at 2.5V or 3.3V, and

the slave LDO2 adjustable voltage

Output Current Range: 0mA ~ 300mA per LDO

PTSSOP-08 Package with Power Pad

High Accuracy Output Voltage: +/- 1.5%

Input Range of 2.6V to 7.0V

regulators developed utilizing CMOS technology. CM2730 ꢀ

contains two LDOs, one with pre-set output voltage (master ꢀ

LDO1), the other with adjustable output voltage (slave LDO2). ꢀ

Each LDO owns its input voltage, bandgap reference voltage,

and protection circuit, which reduce noise and cross talk

between two LDOs. This dual LDO family is featured low

quiescent current (60µA typ.), low dropout voltage, and high ꢀ

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

provides low dropout voltage and large output current. 2.2µF ꢀ

ꢀ

Independent Thermal Shutdown

Power Sequence

Power Good Output Function

or greater can be used as an output capacitors.

ꢀ

The PTSSOP-8 package is recommended for configuring

Independent Bandgap

portable devices and large current application, respectively. ꢀ

Current Limiting

ꢀ

Factory Pre-set Output Voltages

Short Circuit Current Fold-Back

Low Temperature Coefficient

These robust devices are designed to prevent device failure ꢀ

under the worst operation condition with both Thermal

Shutdown and Current Fold-back.
