CS5253-1GDP5

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The CS5253-1GDP5 is a 3.0 A adjustable linear regulator (LDO) manufactured by onsemi, housed in a 5-pin package. It features a very low dropout voltage of less than 0.40 V at full load, achieved through separate powering of the internal pass transistor and control circuitry. The output voltage range spans from 1.25 V to 5.0 V with a 1.0% trimmed reference for precision. Key electrical characteristics include fast transient response and remote voltage sensing capabilities. The device integrates thermal shutdown, current limit, and short circuit protection to ensure robust operation under various load conditions.
