3 Description
The LM2936Q ultralow 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 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 LM2936Q is available in
8-pin SOIC and VSSOP packages, a 4-pin SOT–223
package, as well as a 3-pin TO-252 surface mount
package.

* Required if regulator is located more than 2 inches from power supply filter capacitor.
** Required for stability. See Electrical Characteristics for 3-V LM2936Q for required values. Must be rated over
intended operating temperature range. Effective equivalent series resistance (ESR) is critical, see Typical
Characteristics. Locate capacitor as close to the regulator output and ground pins as possible. Capacitance may be
increased without bound.
