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
operated systems. The LM2936 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 LM2936 has
a 40V maximum operating voltage limit, a −40˚C to +125˚C
operating temperature range, and ±3% output voltage toler-
ance over the entire output current, input voltage, and tem-
perature range. The LM2936 is available in a TO-92 pack-
age, a SO-8 surface mount package, and a TO-252 surface
mount power package.
Features
n Ultra low quiescent current (IQ ≤ 15 µA for IO = 100 µA)
n Fixed 5V, 50 mA output
n ±2% Initial output tolerance
n ±3% Output tolerance over line, load, and temperature
n Dropout voltage typically 200 mV @ IO = 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
n 60V operating voltage limit for LM2936HV
n Shutdown Pin available with LM2936BM package
Typical Application
* Required if regulator is located more than 2" from power supply filter capacitor.
00975901
** 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.
