概述

Description

LT1761ES5-3#TRPBF is a fixed-output, high‑current low‑dropout regulator from Linear Technology (now Analog Devices). The “-3” in the name indicates a 3.3 V fixed output. It can source up to about 3 A and is designed to regulate from a relatively high input voltage with a low dropout voltage at full load. Key features typically include:
- Fixed 3.3 V output (you can also choose adjustable variants in other part numbers)
- Output current up to ~3 A
- Enable/SHDN input to turn the regulator on/off
- Protection: current limit and thermal shutdown
- Wide input voltage range (up to about 36 V in many versions)
- Remote-sense and/or stability options depending on exact variant
Packaging/code:
- ES5 refers to the package style
- #TRPBF indicates Tape & Reel Pb-free packaging
Applications: point‑of‑load regulation for microprocessors/FPGA logic, embedded systems, automotive/industrial supplies.
For exact pinout, package details, and precise electrical specs, consult the LT1761ES5-3 datasheet.

Features

Key features of LT1761ES5-3#TRPBF (Fixed 3.3V version in ES5 package, Pb-free):
- Fixed output: 3.3 V
- Output current: up to about 1.5 A
- Input voltage range: up to 36 V
- Low dropout voltage (high efficiency at moderate loads)
- Enable pin for remote on/off control
- Overcurrent protection and thermal shutdown
- Low noise with good line/load regulation and fast transient response
- High PSRR for clean output
- 5-pin ES5 package (SOT-23-5) with Pb-free/TR tape-and-reel packaging
Note: For exact electrical specs (dropout at specific currents, precise quiescent current, regulation tolerances, etc.), please consult the official datasheet.

Package

8-pin MSOP package. TRPBF means Tape-and-Reel, RoHS-compliant (lead-free) packaging.

Pinout

- Pin count: 5 pins (SOT-23-5/ES5 package).
- Function: Fixed-output low-dropout linear regulator (LT1761) with 3.3V output, enable/shutdown control, up to about 1.5A output capability (input range up to ~40V).

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI).
- What kind of company: A global semiconductor company that designs and manufactures analog, mixed-signal, and power-management ICs (the LT1761 originated with Linear Technology, now part of ADI).

Application

Typical applications for LT1761ES5-3#TRPBF (3.3V fixed LDO):
- Point-of-load regulator for microprocessors, DSPs, FPGAs, and other digital ICs
- Battery-powered portable devices needing a compact 3.3V rail
- Post-regulation stage for switching regulators to improve ripple/PSRR
- Analog/mixed-signal circuits (op-amps, ADCs/DACs, instrumentation) requiring clean 3.3V
- Automotive/industrial/consumer electronics that need a small, efficient 3.3V LDO
