概述

Description

TPS7B8133DGNR is a Texas Instruments fixed-output low-dropout regulator (LDO) from the TPS7B family. It provides a precise 3.3-V output with low dropout and low noise, designed for robust, compact 3.3-V rails in automotive and industrial electronics. Key features typically include enable control, protection and reliability options (overcurrent/short-circuit protection, thermal shutdown, reverse-current protection), and good power-supply rejection. The DGNR suffix denotes the specific package/leadframe for this device. Common applications are microcontroller and FPGA/SoC power rails, sensors, and other circuits requiring a stable 3.3-V supply in challenging environments. For exact electrical specs (input range, quiescent current, dropout, PSRR, enable threshold, and package details), consult the latest TI datasheet. If you’d like, I can summarize the precise numbers once you share the datasheet or a link.

Features

TPS7B8133DGNR features:
- Fixed 3.3-V output LDO
- Low dropout for efficient operation
- Enable (EN) pin to enable/disable regulator
- Very low quiescent current
- Overcurrent/short-circuit protection with current limit
- Thermal shutdown protection
- Input UVLO protection for reliable startup
- Output reverse-current protection
- Stable with minimal external components
- Small DGNR package suitable for compact designs

Package

VSON-8 (3×3 mm) lead-free package; NR suffix indicates the RoHS, Tape-and-Reel variant.

Pinout

- Pin count: 8 pins (VSON-8 package)
- Function: Fixed-output 3.3 V low-dropout regulator (LDO) with an enable input. It uses IN, OUT, GND, EN pins (other pins are typically NC/reserved) and includes protection features (overload/thermal).

Manufacturer

Manufacturer: Texas Instruments (TI).
What kind of company: TI is an American multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits.

Application

TPS7B8133DGNR is a fixed 3.3-V LDO regulator.
- Applications: power microcontrollers/MPUs/FPGA/ASICs and memories; ADC/DAC front-ends and analog/RF circuits; sensors; portable/embedded devices; automotive and industrial electronics needing a clean 3.3-V rail.
- Highlights: low noise, good PSRR, fast transient response, with enable and protection features suitable for post-regulation and noise-sensitive subsystems.
