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.
