LM2936-5.0
Ultra-Low Quiescent Current 5V Regulator
LM2936-5.0
Ultra-Low Quiescent Current 5V Regulator
General DescriptionThe LM2936 ultra-low quiescent current regulator features
low dropout voltage and low currentin the standby mode.
With less than15µA quiescent currentata 100µA load,the
LM2936is ideally suitedfor automotive and other battery
operated systems. The LM2936 retainsallof the features
that are commonto low dropout regulators includinga low
dropout PNP pass device, short circuit protection, reverse
battery protection, and thermal shutdown. The LM2936 has 40V maximum operating voltage limit,a −40˚Cto +125˚C
operating temperature range, and ±3% output voltage toler-
ance over the entire output current, input voltage, and tem-
perature range. The LM2936is availableina TO-92 pack-
age,a SO-8 surface mount package, anda TO-252 surface
mount power package.
Features Ultra low quiescent current(IQ≤15µAforIO= 100 µA) Fixed5V,50 mA output ±2% Initial output tolerance ±3% Output tolerance over line, load, and temperature Dropout voltage typically 200 mV@IO =50 mA Reverse battery protection −50V reverse transient protection Internal short circuit current limit Internal thermal shutdown protection 40V operating voltage limit 60V operating voltage limitfor LM2936HV Shutdown Pin available with LM2936BM package
Typical Application00975901 Requiredif regulatoris located more than2" from power supply filter capacitor. Requiredfor stability. Mustbe ratedfor10µF minimum over intended operating temperature range. Effective series resistance (ESR)is critical,see
curve. Locate capacitoras closeas possibletothe regulator outputand ground pins. Capacitance maybe increased without bound.
