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.

Simplified Schematic

* 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.
