Ultra-Low Quiescent Current LDO Voltage Regulator

General Description

The LM2936Q 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

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 40V maximum operating voltage limit, a −40°C to +125°C

operating temperature range, and ±3% output voltage toler-

ance over the entire output current, input voltage, and tem-

perature range. The LM2936Q is available in a SO-8

package.

Typical Application

* Required if regulator is located more than 2 from power supply filter capacitor.

** Required for stability. See Electrical Characteristics for required values. Must be rated over intended operating temperature range. Effective series resis-

tance (ESR) is critical, see curve. Locate capacitor as close as possible to the regulator output and ground pins. Capacitance may be increased without

bound.
