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.
