LM2936-3.3
Ultra-Low Quiescent Current 3.3V Regulator
LM2936-3.3
Ultra-Low Quiescent Current 3.3V Regulator
General DescriptionThe LM2936-3.3 ultra-low quiescent current regulator fea-
tures low dropout voltage and low currentin the standby
mode. With less than20µA quiescent currentata 100µA
load, the LM2936-3.3is ideally suitedfor automotive and
other battery operated systems. The LM2936-3.3 retainsall the features that are commonto low dropout regulators
includinga low dropout PNP pass device, short circuit pro-
tection, reverse battery protection, and thermal shutdown.
The LM2936-3.3 hasa 40V maximum operating voltage
limit,a −40˚Cto +125˚C operating temperature range, and
±3% output voltage tolerance overthe entire output current,
input voltage, and temperature range. The LM2936-3.3is
availableina TO-92 package,a SO-8 surface mount pack-
age,as wellas SOT-223 and TO-252 surface mount power
packages.
Features Ultra low quiescent current(IQ≤20µAforIO= 100 µA) Fixed 3.3V,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 Shutdownpin available with LM2936BM package
Typical Application10132401 Requiredif regulatoris located more than2" from power supply filter capacitor. Requiredfor stability. Mustbe ratedfor22µF 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.
