概述

Description

MIC5209-5.0YM is a fixed 5.0 V low-dropout linear regulator from Microchip/Micrel. It supplies a regulated 5 V rail from a higher input (typical range up to ~16 V) with a small dropout voltage at load. It can source tens to ~150 mA (check datasheet for the exact max) and includes an enable/shutdown input to reduce quiescent current when off. Protection features usually include current limit and thermal shutdown for robustness. Stability requires a decoupling input cap and an output capacitor (commonly 2.2–10 µF, per datasheet). The YM suffix denotes a specific small-package variant (a compact SOT-23/5 style) suitable for surface-mount designs. Applications: portable devices, embedded systems, and other circuits needing a compact, inexpensive 5 V regulator.

Features

MIC5209-5.0YM features:
- Fixed 5.0 V output low-dropout regulator (LDO) in a 5-pin SOT-23 (YM) package
- Output current capability up to about 550 mA
- Low dropout voltage for efficient operation
- Low quiescent current and low output noise with good PSRR
- Enable pin for shutdown/enable control
- Short-circuit protection and thermal shutdown
- Overcurrent protection
- Suitable for battery-powered and compact applications

Package

MIC5209-5.0YM is in a 5-pin SOT-23-5 package (SC-70-5 form factor).

Pinout

- Pin count: 5 (SOT-23-5 package, YM code)
- Function: Fixed 5.0 V low-dropout regulator (LDO). Pins provide Vin, Vout (5.0 V), GND, Enable (EN), and a No-Connect pin in this package. EN controls regulator enable/disable.

Manufacturer

Manufacturer: Microchip Technology (formerly Micrel, Inc.).
Company type: An American multinational semiconductor company that designs, develops, and manufactures microcontrollers, memory, analog, and power-management ICs.

Application

Typical application areas for MIC5209-5.0YM: fixed 5V LDOs for battery-powered devices; power rails for microcontrollers, DSPs, sensors, and ADC/DAC front-ends; analog/mixed-signal circuits needing a clean, low-noise 5V supply; embedded systems, development boards, portable instruments, and small USB peripherals.
