Battery-Powered Application

DESCRIPTION

The SS8014-xxG is a low supply-current, low-dropout linear

regulator that comes in a space-saving SOT23-5 package.

The supply current at no-load is 55µA. In the shutdown

mode, the maximum supply current is less than 1µA.

Operating voltage range of the SS8014 is from 2.5V to

5.5V. The over-current protection limit is set at 500mA

typical and 400mA minimum. An over-temperature pro-

tection circuit is built-in to the SS8014 to prevent thermal

overload. These power saving features make the SS8014

ideal for use in such battery-powered applications as

notebook computers, cellular phones, and PDA’s.
