Applications

Low Voltage "Core" Processors Peripheral Adapter Cards Portable/Battery-Powered Devices 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 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.

DESCRIPTION

A logic input control to enable the regulator output. When EN is asserted (logic high), it allows out- put regulation to commence. When EN is deasserted (logic low), the regulator pass transistor (N- channel MOSFET) is forced into a high impedance mode. All other internal circuitry is unaffected by the state of the EN input and will always remain powered whenever VCC is present. An internal pull-up current (2µA) from VCC must be overdriven in order to apply a Logic Low to the EN control input. The EN control input is intended to be used for power-up sequencing. VCC The input power supply for the regulator. If this input is within a few inches of the main supply filter, a capacitor may not be necessary. Otherwise an input filter capacitor of approximately 1uF to 10uF will ensure adequate filtering. VOUT The regulator voltage output used to power the load. A nominal output capacitor of 10uF is suffi- cient to minimize any transient disturbances under normal operating conditions. Additional output capacitance can be used to further improve transient load response. N.C. These pins have no connection to the internal device. To provide additional thermal performance, these pins can be connected directly to the PC board GND plane. 5,6,7,8 GND The negative reference for all voltages.

The power rating is based on a printed circuit board heat spreading capability equivalent to 2 square inches of copper connected to the GND pins. Typical multi-layer boards using power plane construction will provide this heat spreading ability without the need for additional dedicated copper area.
