Product Description

The CM3002 family of regulators are very low dropout regulators that deliver up to 1.0A of load current at a fixed voltage output. Input and output voltage options for the CM3002 family devices are presented in Table 1.

Operating from a single input supply, these devices are ideally suited for powering low voltage “core” proces sors, especially where a 3.3V source is already available.

These regulators feature a dedicated control input (EN, Active High) for power-up sequencing flexibility. When this input is taken low, the regulator output is disabled. In this state, the supply current will drop to a low level to ensure all the internal control circuitry still remains active. This provides excellent start-up response when ever the device comes out of shutdown.
