Übersicht

Description

AZ1117R-3.3TRE1 is a fixed 3.3 V low‑dropout linear regulator in the AZ1117 family (LM1117‑3.3 compatible). It can deliver up to about 1 A with a dropout of ~1.1–1.3 V at full load and supports input voltages up to ~15 V. The TRE1 suffix indicates Tape & Reel packaging for automatic assembly; devices are offered in three‑pin SOT‑223/TO‑263 type packages. Pinout (viewing the front): pin1 = ground/adjust, pin2 = Vout = 3.3 V, pin3 = Vin; the tab is Vin. It requires an output capacitor (typically ≥10 µF, low ESR) close to the regulator, and an input capacitor near Vin for stability. Good for supplying microcontrollers and digital logic from higher voltage rails. Always check the datasheet for exact electrical specs, ESR requirements, and thermal considerations.

Features

Key features of AZ1117R-3.3TRE1 (3.3V fixed LDO):
- Fixed output: 3.3 V
- Output current: up to ~1 A
- Dropout voltage: ~1.1–1.3 V at full load
- Input range: ~4.75–15 V (typical)

Note: AZ1117R-3.3TRE1 is a fixed 3.3 V LDO regulator.

Manufacturer

AZ1117R-3.3TRE1 is manufactured by AZ Components (AZ). AZ Components is a Chinese electronics/semiconductor company that designs and manufactures integrated circuits and electronic components, including voltage regulators like the AZ1117 series.

Application

AZ1117R-3.3TRE1 is a fixed 3.3V LDO regulator. Applications include:
- Generating a 3.3V rail from higher inputs (typically 4.75–15V) for embedded systems
- Powering microcontrollers, digital ICs, sensors, ADC/DACs, and memory
- Supplying 3.3V in consumer electronics (routers, set‑top boxes, audio/video gear), displays, and LED drivers
- Prototyping on development boards
- General, compact 3.3V regulation (with proper input/output capacitors)
