Ultra-Low Quiescent Current LDO Voltage Regulator
General Description
The LM2936Q 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
LM2936Q is ideally suited for automotive and other battery
operated systems. The LM2936Q 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 LM2936Q 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 LM2936Q is available in a SO-8
package, SOT-223 surface mount package and TO-252 sur-
face mount package.

Typical Application
* Required if regulator is located more than 2″ from power supply filter capacitor.
30131901
** Required for stability. See Electrical Characteristics for required values. Must be rated over intended operating temperature range. Effective series resis-
tance (ESR) is critical, see curve. Locate capacitor as close as possible to the regulator output and ground pins. Capacitance may be increased without
bound.
