概要
Description
TPS79625DCQ is a fixed-output low-dropout regulator from TI’s TPS796xx family. It provides a regulated 2.5 V rail from a higher input (typical max ~6 V). Key features:
- 2.5 V fixed output
- Low dropout (typical ~150 mV at moderate current)
- Enable pin for shutdown
- Low quiescent current with protection (short-circuit, thermal shutdown)
- Good line/load regulation
- Package: DCQ (8-pin VSSOP) with exposed pad
Typical use: power a 2.5 V subsystem in portable devices, microcontrollers, sensors, and other small electronics. Operation is simple: apply input, drive EN to enable, and the regulator maintains a stable 2.5 V across load changes. For exact electrical specs, consider the datasheet and derating guidelines.
