General Description
CM2830A General Description
The CM2830/CM2830A family is a positive voltage linear regulator developed utilizing CMOS technology featured low quiescent current (30µA typ.), low dropout voltage, and high output voltage accuracy. Built-in low on-resistance transistor provides low dropout voltage and large output current. A 2.2µF 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.
