Visão Geral

Description

LP3985IM5-5.0 is a fixed-output low-dropout regulator (LDO) in the LP3985 family. It provides a regulated 5.0 V output to power microcontrollers, sensors, and other logic from a higher input voltage, in a compact package.
Key points:
- Fixed output: 5.0 V
- Low dropout with good line/load regulation
- Output current capability in the tens–hundreds of milliamps (depends on package and heat)
- Protection: short-circuit and thermal shutdown
- Stable with ceramic capacitors; requires an input cap and an output cap per datasheet
- Available in small packages (e.g., SOT-23/SC-70 variants)
Typical use: compact 5 V regulator for MCU rails, peripherals, or analog/digital circuits on space-constrained boards.
Note: for exact pinout, input/output voltage range, dropout at your load, quiescent current, and capacitor recommendations, consult the LP3985IM5-5.0 datasheet.

- Very low quiescent (bias) current
- Protection: overcurrent/short-circuit protection
- Thermal shutdown protection
- Stable with low-ESR output capacitors (ceramics)
- Small IM package footprint
Note: exact electrical specs and package options vary; refer to the datasheet for precise numbers and capacitor requirements.

Pinout

- Pin count: 5 pins (SOT-23-5 package)
- Function: Fixed 5.0 V low-dropout regulator (LDO) that provides a regulated 5 V output from a higher input voltage.
