LM2931T-5.0G

LM2931T-5.0G Description

The LM2931T-5.0G from onsemi is a fixed-output linear voltage regulator designed to deliver a stable 5V output with a maximum input voltage of 26V. Capable of supplying 100mA of continuous output current, this regulator is optimized for low-power applications where efficiency and reliability are critical. It features a low dropout voltage of 0.6V @ 100mA, ensuring efficient operation even when the input voltage is close to the output level. With a quiescent current of just 1 mA, the LM2931T-5.0G minimizes power dissipation, making it ideal for battery-powered systems. Its 90dB PSRR (120Hz) ensures excellent noise rejection, critical for sensitive analog and digital circuits.
