3 Description
The LM2936 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 LM2936 is ideally suited for automotive and other battery operated systems. The LM2936 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 LM2936 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 LM2936 is available in a TO-92 through-hole package, as well as SOIC-8, VSSOP, SOT–223, and TO-252 surface mount packages.

Simplified Schematic
** Required for stability. See Electrical Characteristics for 3-V LM2936 for required values. Must be rated over intended operating temperature range. Effective series resistance (ESR) is critical, see Typical Characteristics. Locate capacitor as close as possible to the regulator output and ground pins. Capacitance may be increased without bound.
