MIC2954-08YM

The MIC2954-08YM is an 8‑pin low‑dropout linear regulator from Micrel (now Microchip) in the MIC2954 family. The “-08YM” suffix identifies the 8‑pin package (MSOP/SO‑8); the exact output voltage and detailed specs depend on the specific fixed or adjustable variant, which you’ll find in the datasheet. Key features typically include overcurrent protection, thermal shutdown, and a low dropout voltage, making it suitable for supplying a stable voltage to microcontrollers, analog circuitry, and other ICs from a higher input rail. It requires appropriate input and output capacitors (per the datasheet) and may include an enable or adjust pin depending on the variant. For precise electrical characteristics (max input voltage, dropout, quiescent current, current limit, and application notes), consult the MIC2954 data sheet and the exact -08YM variant section. In short: it’s an 8‑pin LDO regulator family member used to generate a regulated voltage with protection features; verify the exact Vout and pinout from the datasheet.

Here are the typical features of the MIC2954-08YM fixed-output regulator:
- Fixed output voltage: 8.0 V
- Output current: up to about 150 mA
- Low dropout regulator
- Protection: current limit and thermal shutdown
- Wide input voltage range (up to about 26 V)
- No external components required for fixed version
- Packaging: 8-pin YM (SOP-8/8-pin) package
Note: exact numbers can vary slightly by lot and datasheet revision.

- Pin count: 8 pins (SOIC-8 package, -08YM)
- Function: 3-A positive low-dropout linear regulator with enable/shutdown and built-in protection (current limit and thermal shutdown). Provides regulated output from an input voltage, with variant options for different fixed outputs or adjustable configurations.

Manufacturer: Micrel Semiconductor (now part of Microchip Technology).
About: Micrel was a fabless semiconductor company specializing in analog and mixed-signal ICs (power management, voltage regulators, high-speed/alignment ICs). Microchip Technology, a global semiconductor company, acquired Micrel in 2015 and continues to market these products.

MIC2954-08YM is a low-dropout, 150 mA LDO regulator in a compact YM package. Typical applications:
- Power rails for portable, battery-powered electronics
- Local regulation for microcontrollers, DSPs, RAM and logic in embedded systems
- Biasing and supplies for analog front-ends, ADC/DACs and sensors
- Post-regulation for RF/IF modules and other noise-sensitive circuits
- General-purpose regulator in consumer electronics where space and low quiescent current matter
Note: supports fixed/adjustable outputs depending on the variant.

The MIC2954-08YM comes in an 8-pin surface-mount package (SO-8).
