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 100 mA). Other features include the logic-compatible
on/off input which enables the regulator to be swit ched 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
for a 5V, 4.8V, 4.5V, 4V, 3.5V, 3.3V, 3V, 2.5V or programmed
from 3V to 24V with an external pair of resistors. For other fix
voltages cons ult the f act or y.
