1 / 9 page LM2936-5.0 Ultra-Low Quiescent Current 5V Regulator General Description The LM2936 ultra-low quiescent current regulator features low dropout voltage and low current in the standby mode. With less than 15 µA quiescent current at a 100 µA load, the LM2936 is ideally suited for automotive and other battery op- erated systems. The LM2936 retains all of the features that are common to low dropout regulators including a low drop- out PNP pass device, short circuit protection, reverse battery protection, and thermal shutdown. The LM2936 has a 40V maximum operating voltage limit, a −40˚C to +125˚C operat- ing temperature range, and ±3% output voltage tolerance over the entire output current, input voltage, and tempera- ture range. The LM2936 is available in a TO-92 package, a SO-8 surface mount package, and a TO-252 surface mount power package. Features n Ultra low quiescent current (I Q ≤ 15 µA for IO ≤ 100 µA) n Fixed 5V, 50 mA output n Output tolerance ±3% over line, load, and temperature n Dropout voltage typically 200 mV @ I O = 50 mA n Reverse battery protection n −50V reverse transient protection n Internal short circuit current limit n Internal thermal shutdown protection n 40V operating voltage limit Typical Application Connection Diagrams DS009759-1 * Required if regulator is located more than 2" from power supply filter capacitor. ** Required for stability. Must be rated for 10 µF minimum over intended operating temperature range. Effective series resistance (ESR) is critical, see curve. Locate capacitor as close as possible to the regulator output and ground pins. Capacitance may be increased without bound.
