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 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.
