LM2936-3.0  
Ultra-Low Quiescent Current 3.0V Regulator  
General Description  
Features  
n Ultra low quiescent current (IQ 20 µA for IO = 100 µA)  
n Fixed 3.0V, 50 mA output  
The LM2936-3.0 ultra-low quiescent current regulator fea-  
tures low dropout voltage and low current in the standby  
mode. With less than 20 µA quiescent current at a 100 µA  
load, the LM2936-3.0 is ideally suited for automotive and  
other battery operated systems. The LM2936-3.0 retains all  
of the features that are common to low dropout regulators  
including a low dropout PNP pass device, short circuit pro-  
tection, reverse battery protection, and thermal shutdown.  
The LM2936-3.0 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 LM2936-3.0 is  
available in a TO-92 package, a SO-8 surface mount pack-  
age, as well as SOT-223 and TO-252 surface mount power  
packages.

Typical Application  
20001601  
* Required if regulator is located more than 2" from power supply filter capacitor.  
*
*
Required for stability. Must be rated for 22 µF minimum over intended operating temperature range. Effective series resistance (ESR) is critical, see  
curve. Locate capacitor as close as possible to the regulator output and ground pins. Capacitance may be increased without bound.
