EC49124-500mA Super Linear Regulator

General description

The EC49124 is an efficient linear voltage regulator. It has extra low dropout voltage. At light loads the typical dropout voltage is 15mV, at full load the typical dropout voltage is 800mV. The output voltage accuracy is better than 2%.The EC49124 has low ground current at 65uA, so it can help prolong battery life. The EC49124 is specially designed for hand-held, battery-powered devices.
