LM2936-3.3  Product Folder

The LM2936-3.3 ultra-low quiescent current regulator features low dropout voltage and low current in the standby mode. With less than 20 µA quiescent current at a 100 µA load, the LM2936-3.3 is ideally suited for automotive and other battery operated systems. The LM2936-3.3 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 LM2936-3.3 has a 40V 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 LM2936-3.3 is available in a TO-92 package, a SO-8 surface mount package, as well as SOT-223 and TO-252 surface mount power packages.
