Description

The CM2730 dual LDO family are positive linear voltage 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 or greater can be used as an output capacitors.
 
The PTSSOP-8 package is recommended for configuring portable CM2730 and large current application, respectively. 
 
These robust CM2730 are designed to prevent device failure under the worst operation condition with both Thermal Shutdown and Current Fold-back.
