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.
