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” processors, 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 whenever the device comes out of shutdown. The CM3002 family of regulators is fully protected, offering both overload current limiting and high temperature thermal shutdown. Housed in space saving thermally-enha...
