Linear & Switching Voltage Regulators

LM2931AM-5.0/NOPB Description

The LM2931AM-5.0/NOPB from Texas Instruments is a fixed 5V, 100mA low-dropout (LDO) linear voltage regulator designed for applications requiring stable power with minimal input-output differential. It operates over a wide input voltage range (up to 26V) and delivers a fixed 5V output with a low dropout voltage of 0.3V at 100mA, making it ideal for battery-powered and automotive systems. The device features reverse polarity protection, over-temperature shutdown, and short-circuit protection, ensuring robust performance in harsh environments. Packaged in an 8-pin SOIC tube, it is RoHS3 compliant and rated for MSL 1 (unlimited shelf life).
