Description

LT1761MPS5-5#TRPBF is the fixed‑output 5.0V version of Linear Technology’s LT1761 high‑current, low‑dropout regulator. It is offered in an 8‑pin MPS (MSOP‑8) Pb‑free package and comes in Tape & Reel (TRPBF) packaging.
Key features include high output capability, low dropout, fast transient response, and built‑in protection (current limit and thermal shutdown). The fixed 5V version uses internal feedback, so external resistors are not required.
Typical applications: point‑of‑load regulation for digital processors, FPGAs, telecoms, and battery-powered systems needing a compact, robust 5V regulator.
How to use: connect VIN to the input supply, VOUT to the load via the recommended output capacitor, and GND to ground. Use the EN/Shutdown pin to enable/disable as needed. Follow the datasheet for exact pinout and capacitor requirements to ensure stability.
Note: “TRPBF” denotes Tape & Reel, Pb‑Free packaging; verify current availability and packaging with your distributor.

Package

MSOP-5: a 5-lead MSOP package, provided in Tape-and-Reel Pb-Free (TRPBF) packaging.

Pinout

Pin count: 5 pins.
Pin functions:
- VIN — regulator input (unregulated supply).
- VOUT — regulated 5.0 V output.
- GND — ground/thermal return.
- ON/OFF (EN) — enable/shutdown control (logic level disables/enables the regulator).
- ADJ/FB — feedback/adjust pin (used to set output on adjustable versions; on the fixed 5.0 V variant it is internally tied/handled).

Manufacturer

Manufacturer: Analog Devices, Inc. (part originally from Linear Technology — LT).
Type of company: A multinational semiconductor firm that designs and manufactures analog, mixed‑signal and power‑management integrated circuits (including LDO regulators), serving industrial, communications, automotive and consumer markets.

Application

LT1761MPS5-5#TRPBF is a fixed 5V, low-noise LDO. Typical applications:
- Point-of-load regulation for microprocessors, microcontrollers, and FPGAs
- Clean supply for ADC/DAC analog front-ends
- Bias/reference supplies for op-amps and RF/mixed-signal circuits
- Battery-powered/portable devices requiring compact, efficient regulation
- Telecom/networking and instrumentation rails needing a stable 5V with good transient response

Equivalent

There’s no guaranteed exact drop‑in replacement for LT1761MPS5‑5. Common functional substitutes (5.0 V LDOs with similar low‑noise/LDO roles) include Microchip MIC5219‑5.0, ON Semiconductor NCP4681‑5.0, and TI TPS7A05‑5.0. Verify pinout, dropout, quiescent current, output current and thermal specs before substituting.
