DESCRIPTION

The CLM2805 is a low power voltage regulator. This product is designed for battery-powered applications such as cordless telephones, radio control systems and portable computers. The CLM2805 features very low quiescent current (0.4mA) and very low dropout put voltage (typ. 50mV at a light load of 300mV at 100mA). Other features include the logic-compatible on/off input which enables the regulator to be switched on and off. The CLM2805 is offered in an ultra small package, 5-pin SOT-23 as a fixed, adjustable with ON/OFF Switch. The regulator output voltage may be internally pin-strapped from 3V to 24V with an external pair of resistors. For other fix voltages consult the factory.
