LM9036

LM9036 Ultra-Low Quiescent Current Voltage Regulator April 2004 LM9036 Ultra-Low Quiescent Current Voltage Regulator General Description The LM9036 ultra-low quiescent current regulator features low dropout voltage and low current in the standby mode. With less than 25µA Ground Pin current at a 0.1mA load, the LM9036 is ideally suited for automotive and other battery operated systems. The LM9036 retains all of the features that are common to low dropout regulators including a low dropout PNP pass device, short circuit protection, reverse battery protection, and thermal shutdown. The LM9036 has a 40V maximum operating voltage limit, a −40˚C to +125˚C operating temperature range, and ± 5% output voltage tolerance over the entire output current, input voltage, and temperature range. Features n Ultra low Ground Pin current (IGND ≤ 25µA for IOUT = 0.1mA) n Fixed 5V, 3.3V, 50mA output n Output tolerance ± 5% over line, load, and temperature n Dropout voltage typically 200mV @ IOUT = 50mA n −45V reverse transient protection n Internal short circuit current limit n Internal thermal shutdown protection n 40V operating voltage limit Typical Application 20001101 * Required if regulator is located more than 2" from power supply filter capacitor. ** Required for stability. Must be rated over intended operating temperature range. Effective series resistance (ESR) is critical, see Electrical Characteristics. Locate capacitor as close as possible to the regulator output and ground pins...
