概述

Description

The TPS76833QPWP is TI’s fixed 3.3 V low-dropout regulator in the TPS768 family. It accepts a supply input typically from 2.5 V up to 5.5 V and delivers a stable 3.3 V output, with low dropout suitable for battery-powered and space‑constrained designs. It includes standard LDO protections such as enable control, current limiting, thermal shutdown, and short‑circuit protection. The device is designed for very low quiescent current, helping maximize battery life in portable applications. The suffix QPWP denotes a specific TI packaging/variant; check the datasheet for exact package type, pinout, and mechanical details. Common applications include powering microcontrollers, sensors, memory, and other components that require a clean, constant 3.3 V rail on compact boards. For exact electrical specs (min/max input, dropout at load, quiescent current, and protection thresholds) refer to the TPS76833QPWP datasheet.

Features

TPS76833QPWP is a fixed 3.3-V low-dropout regulator (LDO) from TI. Key features:
- Fixed 3.3 V output
- Input range up to 5.5 V
- Ultra-low quiescent current (battery-friendly)
- Low dropout voltage for efficient operation
- Enable pin for shutting down the regulator
- Built-in protections: current limit and thermal shutdown
- Stable with ceramic output capacitors (low ESR)
- Fast transient response
- Available in small, lead-free, package options (QPWP) suitable for compact designs
Ideal for portable and space-constrained apps requiring a simple, efficient 3.3-V supply.

Package

TPS76833QPWP uses a 6-pin X2SON (VSON) package, about 2.9 × 2.9 mm, with an exposed pad.

Pinout

- Pin count: 5 pins
- Function: Fixed 3.3-V low-dropout (LDO) regulator in a SOT-23-5 package with an enable pin (EN) for on/off control; provides regulated 3.3-V output from the input with GND reference.

Manufacturer

- Manufacturer: Texas Instruments (TI)
- Company type: American multinational semiconductor company that designs and manufactures analog and digital integrated circuits, with a focus on power management, sensors, and signal processing.

Application

TPS76833QPWP is a 3.3 V fixed low-dropout regulator. Common applications: portable and battery-powered devices (wearables, IoT sensors); power rails for microcontrollers, DSPs, and SoCs; analog/mixed-signal sensor front-ends; RF/communications modules; and post-regulation for switching regulators in consumer electronics and industrial equipment needing a clean 3.3 V rail.

Equivalent

Equivalent 3.3 V LDO regulators with similar specs (≈150 mA, low quiescent):
- TI: TPS78033, TPS76333 (low-dropout)
- Analog Devices: ADP3333
- Microchip: MCP1700-33
- ST: LD3985-3.3 or LD1117-3.3 (common substitutes)
- AMS: AMS1117-3.3
Note: verify dropout, quiescent current, package, and pinout to ensure true replacement.
