LT1761MPS5-5

The LT1761MPS5-5 is Linear Technology’s fixed-output low-dropout regulator (LDO). The MPS5-5 designation indicates the MSOP‑8 package variant with a 5‑V fixed output. It accepts a higher input voltage and provides a regulated 5‑V rail with low dropout, good transient response, and built‑in protection features (e.g., current limit, thermal shutdown). It also typically offers an enable control for on/off operation. This part is well-suited for deriving a 5‑V supply in battery-powered or automotive systems, microcontroller and peripheral rails, and other compact, reliable 5‑V regulator needs. For exact electrical specs (input range, dropout, quiescent current, max output current, and the precise pinout), refer to the LT1761 datasheet for the MPS variant.

Here are the key features of LT1761MPS5-5 (fixed 5V output):
- Fixed 5V output version of the LT1761
- Internal 3A switch-mode buck regulator
- Wide input range suitable for automotive/industrial use
- High efficiency with fast transient response
- Current-mode control with fixed switching frequency
- Protections: overcurrent limit and thermal shutdown
- Enable (SHDN) input to disable the device
- Internal soft-start to minimize inrush
- External components: inductor and Schottky diode required
- No external compensation needed for fixed output
- Package: MPS5 (MSOP-8 with exposed pad)
Notes: External catch diode and inductor are required for the converter to operate.

- Pin count: 8 pins (MSOP package, MPS).
- Function: Fixed-output 5V low-dropout regulator (LDO) with enable/shutdown capability; converts input to a regulated 5V output.

- Manufacturer: Analog Devices, Inc. (ADI). The LT prefix comes from Linear Technology; ADI acquired Linear Technology in 2017, so LT1761MPS5-5 is now produced under Analog Devices.
- Company type: American multinational semiconductor company that designs and manufactures analog, mixed-signal, and power-management integrated circuits.

LT1761MPS5-5 is a fixed 5V low-dropout regulator. Typical application areas include:
- Point-of-load regulation for microprocessors, DSPs, FPGAs, and other digital ICs
- Post-regulation for switching converters in telecom, networking, and data-communications gear
- Automotive electronics and other 5V automotive subsystems
- Battery-powered and portable instruments needing a stable 5V rail
- Consumer electronics (set-top boxes, displays, peripherals)
- Any system requiring a compact, stable 5V supply with good ripple and transient response
