A Dual CMOS LDO (Low Dropout Regulator) is a type of voltage regulator integrated circuit (IC) that provides two independent LDO voltage regulator channels in a single package. LDO regulators are designed to regulate and stabilize an output voltage, ensuring it remains relatively constant even when the input voltage varies.

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 devices and large current application, respectively.
