DESCRIPTION
The SM74503 is a series of low dropout voltage regulators with a dropout of 1.2V at 800m A of load current. It has the same pin-out as TI's industry standard LM317.
The SM74503 is available in two fixed voltages, 3.3V and 5V.
The SM74503 offers current limiting and thermal shutdown. Its circuit includes a zener trimmed bandgap reference to assure output voltage accuracy to within ±1%.
The SM74503 series is available in SOT-223 and PFM packages. A minimum of 10µF tantalum capacitor is required at the output to improve the transient response and...
