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.
