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 tolerance over the
entire output current, input voltage, and temperature
range. The LM2936Q is available in a SOIC-8
package, SOT-223 surface mount package and PFM
surface mount package.
Typical Application
* Required if regulator is located more than 2″ from power supply filter capacitor.
** Required for stability. See Electrical Characteristics table 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.
