概述

Description

MIC2954-08YM is a fixed‑output low‑dropout linear voltage regulator from Micrel (now Microchip). It yields a steady 8.0 V rail from a input voltage that is higher than 8 V, suitable for moderate‑current applications. The “08” indicates the 8.0 V fixed output; “YM” denotes the packaging/variant.
Key points:
- Fixed 8.0 V output; designed for low‑to‑moderate load currents.
- Low dropout suitable for supplying an 8 V rail from Vin only slightly above 8 V.
- Built‑in protection: current limit and thermal shutdown.
- Needs appropriate input and output capacitors for stability (per datasheet ESR requirements).
- Packaged in small surface‑mount packages; exact pinout depends on the variant.
Use it when you need a simple, reliable 8 V supply in embedded, automotive, or consumer electronics. For exact electrical specs, pinout, and capacitor recommendations, consult the latest Microchip Micrel MIC2954 datasheet.

Features

MIC2954-08YM is Micrel’s high‑current, low‑dropout regulator. Key features:
- 8‑pin YM package
- Fixed and adjustable output options
- Low dropout voltage for efficient operation
- Enable/shutdown control input
- Very low quiescent current
- Output current limit
- Thermal shutdown and safe‑area protection
- Short‑circuit protection
- Stable with a wide range of output capacitors (including ceramics)
- Good line and load regulation
Ideal for battery-powered and portable applications requiring a robust LDO with protection features.

Package

8-pin SOIC (Small-Outline IC) package, surface-mount; Pb-free version.

Pinout

- Pin count: 8 pins (SO-8 package)
- Function: MIC2954-08YM is a Micrel/Microchip MIC2954 series low-dropout (LDO) positive voltage regulator. It provides a regulated output (fixed or adjustable via external resistors) from an input supply, with built-in current limit and thermal shutdown protection.

Manufacturer

Manufacturer: Micrel, Inc. (now part of Microchip Technology).
Micrel was a fabless semiconductor company that designs analog, mixed-signal and power-management ICs. In 2015, Micrel was acquired by Microchip Technology, a global semiconductor company.

Application

Application areas of MIC2954-08YM:
- Low-dropout regulator for microcontrollers, DSPs, op-amps, and analog front-ends
- Power supplies for battery-powered and portable devices
- Sensor interfaces and data-acquisition systems needing clean, stable rails
- Automotive, industrial, and telecom equipment
