LP2957AISX
IC REG LIN 5V 250MA DDPAK/TO263Manufacturer: Texas Instruments
Categories: Linear, Low Drop Out (LDO) Regulators
Quality Control: Learn More
The Texas Instruments LP2957AISX is a positive fixed output linear voltage regulator. This device provides a stable 5V output with a maximum output current of 250mA. It features an enable pin for power management and offers robust protection against over current, over temperature, and reverse polarity conditions. With a quiescent current of 200 µA, it is suitable for battery-powered applications. The input voltage range extends up to 30V, and the dropout voltage is a maximum of 0.8V at the full 250mA load. The LP2957AISX is supplied in a TO-263 (DDPAK-5) surface-mount package, commonly found in automotive, industrial, and consumer electronics applications requiring reliable voltage regulation.
