LP3985IM5-5.0

The LP3985IM5-5.0 is a fixed 5.0 V low-dropout regulator in a 5-pin SOT-23 (IM) package from Torex Semiconductor. It provides a stable 5 V rail from a modest input and typically sources up to about 150 mA, with features aimed at small, battery-powered devices.
Key features
- Fixed 5.0 V output; enable (EN) pin to shut down when not in use; bypass (BYP) pin for reduced output noise.
- Low dropout and low quiescent current.
- Protection: current limit and thermal shutdown for reliability.
- Input range roughly 2.7–6.0 V; dropout on the order of a few hundred mV at rated load (typical values in datasheet).
Pinout (typical)
- VIN, VOUT, GND, EN, BYP.
Usage notes
- Use recommended input and output capacitors close to the device (as specified in the datasheet).
- Enable the device with EN; BYP allows noise reduction if needed.
Applications
- Portable electronics, microcontrollers, sensors, and other 5 V rail requirements in compact spaces.

The LP3985IM5-5.0 comes in a 5‑pin SOT‑23 package (SC‑70‑5).

The LP3985IM5-5.0 is in a 5-pin SOT-23 (M5) package. Pin count: 5. Pin functions:
- IN: unregulated input supply
- OUT: regulated 5.0 V output
- GND: ground reference
- EN (Enable): logic input to enable/disable the regulator (active high)
- BYP (Bypass): noise-reduction bypass node (for a small cap to reduce output noise and improve PSRR)
(Connect IN and OUT with appropriate input/output capacitors and follow the datasheet recommendations for the BYP cap and EN logic.)
