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 avail- able. 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. The CM3002 family of regulators is fully protected, offering both overload current limiting and high temper- ature thermal shutdown. Housed in space saving ther- mally-enhanced SOIC-8 and MSOP-8 (CM3002-33MA/ MF) packages, these devices ensure maximum junc- tion-to-ambient power dissipation. The CM3002 is available with optional lead-free finish- ing.
