概述

Description

ADP3334AR is an Analog Devices fixed-output low-dropout (LDO) regulator, part of the ADP333x family. It provides a 3.3 V output with up to about 250 mA load current, designed for low dropout, low quiescent current, and low-noise output to give a clean supply for sensitive analog/digital circuits. The AR suffix typically denotes a specific packaging option (often tape-and-reel); check the datasheet for the exact package, footprint, and temperature range. Use cases include microcontrollers, digital ICs, ADC/DAC front ends, and other systems requiring a stable 3.3 V rail. For exact electrical specs and packaging, refer to the latest ADP3334AR datasheet.

Features

Here are typical features of the ADP3334AR (low-dropout regulator):
- Fixed 3.3 V output
- Enable/shutdown pin for control
- Wide input range (approx. 2.3–5.5 V or similar)
- Low dropout voltage
- Low quiescent current for efficiency in battery-powered apps
- Good line and load regulation; low output noise
- Short-circuit protection and thermal shutdown
- Reverse-current protection
- Overcurrent protection
- ESD protection on inputs/outputs
- Suitable for extended temperatures (e.g., -40°C to +125°C)
- Package options: 8-pin (e.g., MSOP-8/SOIC-8) with AR suffix variants
Note: exact numbers (current capability, dropout, PSRR, input range) vary by revision and package. Check the latest datasheet for precise specifications.

Package

ADP3334AR comes in an 8‑pin SOIC (surface‑mount) package.

Pinout

Do you mean the Analog Devices part ADP3334AR (specify package, e.g., SOT-23-5 or SC70-5)? I don’t want to give a potentially wrong pinout—tell me the exact package/marking and I’ll provide the pin count and each pin’s function.

Application

ADP3334AR is a low-noise, high-PSRR LDO regulator. Applications include clean supply rails for precision analog/mixed-signal circuits (ADC/DAC references, op-amps, instrumentation), RF/transceiver front ends, microcontrollers/DSPs, and portable/battery-powered devices (wearables, sensors, medical); and automotive sensor systems needing stable, low-noise power.
