概述

Description

TPS7A2518DRVR is a Texas Instruments low-dropout regulator (LDO) in the TPS7A2518 family. It provides a stable, regulated output from a higher input with simple external resistors (adjustable output) or fixed output configurations, and it is offered in the DRVR packaging.
Key points:
- Type: 1-A (typical) LDO with enable control
- Input/output: wide input range with low dropout for proper rail-to-rail operation
- Protections: overcurrent/short-circuit protection and thermal shutdown
- Performance: low quiescent current and low output noise with good power-supply rejection
- Packaging: DRVR (specific package/assembly code from TI)
Common uses:
- Supply rails for microprocessors, microcontrollers, FPGAs, sensors
- Automotive and industrial electronics requiring a simple, robust regulator
Note: exact electrical specs (input range, output voltage options, quiescent current, accuracy) are in the TI TPS7A2518 datasheet. If you need, I can pull those details or summarize the key figures.

Features

TPS7A2518DRVR features (concise):
- Fixed-output, low-noise LDO in a small DRVR package
- Very low dropout suitable for battery-powered designs
- High PSRR and low output noise for clean rails
- Enable (EN) input to disable/enable the regulator
- Quiescent current optimized for efficiency
- Robust protection: current limit, thermal shutdown
- Reverse-current protection (prevent backflow)
- Wide input voltage range to cover typical supply rails
- Tight output regulation and good line/load regulation
- Suitable for compact, space-constrained applications (RF, sensors, IoT)

Package

TPS7A2518DRVR is in an 8‑pin VSON package (VSON‑8) with an exposed pad.

Pinout

Pin count: 8 pins.
Function: TPS7A2518DRVR is an 8-pin low-dropout (LDO) voltage regulator with a fixed 1.8 V output. It provides VIN, VOUT, GND, and an enable (EN) control; the remaining pins are non-functional/no-connect in this package.
