LX8117-25CDD

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

The LX8117-25CDD is a positive fixed linear low-dropout (LDO) voltage regulator manufactured by Microsemi Corporation. It provides a fixed output voltage of 2.5V with a maximum continuous output current of 1.2A. The device supports an input voltage range up to 12V and features a typical dropout voltage of 1.3V at full load. Key electrical specifications include a static current of 10 mA, power supply rejection ratio (PSRR) of 75 dB at 120 Hz, and integrated overcurrent and short-circuit protection. It operates within a temperature range of 0°C to 125°C and is housed in a TO-263-4 (D2PAK) surface-mount package.
