Categories: Linear, Low Drop Out (LDO) Regulators
Quality Control: Learn More
Texas Instruments LP2957ISX is a fixed 5V positive linear voltage regulator with a 250mA output current capability. This device features an enable pin for flexible control and offers robust protection against over current, over temperature, and reverse polarity faults. The quiescent current is specified at 200 µA, with a maximum supply current of 33 mA. Designed for surface mounting, the LP2957ISX is supplied in a TO-263 (DDPAK-5) package, presented on tape and reel. The dropout voltage is 0.8V at a 250mA load. This regulator is suitable for applications in the automotive and industrial sectors.
