DESCRIPTION
The device is a low dropout linear regulation housed in a
small SOT-23-5 package, rated at 500 mW.
An internal P Channel pass transistor is used in order to
achieve low dropout voltage. The device has extremely
low quiescent current (max 50 µA). The device offers high
precision output voltage of 2% at over temperature. The
low quiescent current and dropout voltage make this part
ideal for battery powered applications. In the standby
mode when the device is disabled, the linear regulator only
draws 1 µA (max).
APPLICATIONS
■ Battery Powered Systems
■ Cellular Telephones
■ Pagers
■ Toys
■ Radio Control Systems
