3 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 40-V 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 through-hole
package, as well as SOIC-8, VSSOP, SOT–223, and
TO-252 surface mount packages.

* Required if regulator is located more than 2″ from power supply filter capacitor.
** Required for stability. See Electrical Characteristics for 3-V LM2936 for required values. Must be rated over
intended operating temperature range. Effective series resistance (ESR) is critical, see Typical Characteristics. Locate
capacitor as close as possible to the regulator output and ground pins. Capacitance may be increased without bound.
