Texas LM2936HVBMA-3.3---Low Quiescent Current LDO Voltage Regulator

LM2936HVBMA-3.3

 

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.

Application Information

 

The LM2936 ultra-low quiescent current regulator features low dropout voltage and low current in the standby mode. The LM2936 has a 40-V maximum operating voltage limit, a −40°C to 125°C operating temperature range, –24-V input voltage protection and ±3% output voltage tolerance over the entire output current, input voltage, and temperature range.

 

Typical Application

 

For the LM2936 5-V option, the output capacitor, COUT, must have a capacitance value of at least 10 µF with an equivalent series resistance (ESR) of at least 300 mΩ, but no more than 8 Ω. For the LM2936 3.3-V and 3-V options, the output capacitor, COUT, must have a capacitance value of at least 22 µF with an ESR of at least 300 mΩ, but no more than 8 Ω. The minimum capacitance value and the ESR requirements apply across the entire expected operating ambient temperature range.
