FEATURES
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 tolerance over the
entire output current, input voltage, and temperature
range. The LM2936 is available in a TO-92 package,
SOIC-8 and SOT–223 surface mount packages, and
a PFM surface mount power package.

Typical Application
* Required if regulator is located more than 2″ from power supply filter capacitor.
** Required for stability. See Electrical Characteristics for required values. Must be rated 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.
