LT1761MPS5-5#TRPBF

LT1761MPS5-5#TRPBF is Linear Technology’s fixed-output low-dropout regulator (LDO). It provides a 5V rail from a higher input, up to about 100 mA, with an enable/shutdown control. The MPS5-5 designation indicates the 5-pin MPS (MSOP/SOT‑23‑5) package, and TRPBF means Tape & Reel Pb‑Free.
Key points
- Fixed 5V LDO, 100 mA capability, with enable pin.
- Low dropout, suitable for battery-fed and portable apps.
- Includes protection features (short‑circuit/thermal) typical of LT LDOs.
- Requires a bias/input capacitor and a low‑ESR output capacitor per datasheet.
- Pb‑free, ordered in Tape & Reel (TRPBF).
How to use
- Connect Vin to your source, GND to ground, EN to Vin (to enable).
- Place a suitable input capacitor near VIN and a low-ESR output capacitor close to VOUT (values specified in the datasheet, typically in the µF range).
- Use the fixed 5V output directly to power 5V logic or downstream regulators.
For exact electrical specs, pinout, and recommended capacitors, refer to the LT1761 datasheet and the TRPBF lot/package details.

Here are the key features of LT1761MPS5-5#TRPBF:
- Fixed output: 5.0 V
- Package: MSOP-8 (MPS), Pb-free, Tape & Reel (TRPBF)
- Wide input range suitable for LDO use (up to 36 V typical)
- High output current capability (LDO regulator)
- Low dropout operation with good transient response
- Low quiescent current (low standby power)
- Protection features: overcurrent/short-circuit protection and thermal shutdown
- Tight output accuracy and good PSRR for noise-sensitive applications
Note: For exact electrical specs (dropout, quiescent current, PSRR, current limit, etc.), refer to the official datasheet.

- Pin count: 5 pins.
- Function: Fixed 5V low-dropout regulator (LT1761). Pin roles typically are VIN (input), VOUT (regulated output), GND (ground), EN (enable), and BYP (bypass for noise reduction with an external capacitor). EN can disable the regulator; BYP improves output ripple/noise when used.

Manufacturer: Analog Devices, Inc. (ADI). Type of company: An American multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing integrated circuits (ADI acquired Linear Technology, the original LT brand, in 2017).

LT1761MPS5-5#TRPBF is a fixed 5V, high-current low-dropout regulator in a SOT-23-5/MPS package. Useful in:
