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. For all available packages, see the orderable addendum at the end of the data sheet.
