Texas Instruments LM2936M-5.0 Fixed LDO Voltage Regulator, 5V 50mA, SOIC-8

The Texas Instruments LM2936M-5.0/NOPB is an advanced fixed linear dropout (LDO) voltage regulator designed for applications where ultra-low power consumption is critical. It features an exceptionally low quiescent current, drawing less than 15µA under a 100µA load, making it ideal for battery-powered and always-on systems.

This regulator provides a stable 5V output at up to 50mA of current, with a remarkably low dropout voltage of typically just 200mV. It is built to handle a wide input voltage range from 5.5V to 40V, offering robust performance in demanding environments. Key protection features include internal short-circuit current limiting, thermal shutdown, and comprehensive input protection capable of withstanding -24V continuous and -50V transient events.

Engineered for reliability, it maintains a tight ±3% output voltage tolerance across the entire operating range of line, load, and temperature (-40°C to 125°C). The device uses a PNP pass transistor topology for low dropout and is offered in a compact, surface-mount SOIC-8 package for easy integration into modern circuit designs.

As a green product compliant with environmental standards (no antimony or bromine), it is well-suited for automotive electronics, industrial automation, process control systems, and general power management tasks where efficiency, size, and reliability are paramount.
