MIC39101-5.0YM

MIC39101-5.0YM is a fixed-output low-dropout linear regulator from Micrel (now Microchip). It provides a regulated 5.0 V rail from a higher input, making it suitable for powering microcontrollers and other digital ICs in compact designs. The “-5.0” denotes the 5.0 V fixed output, and the “YM” suffix refers to the specific package variant (a small, surface-mount package). Key features typically include protection features such as overcurrent/short-circuit protection and thermal shutdown, plus stable operation with standard input/output capacitors (low-ESR). Common applications are battery-powered and portable electronics, embedded systems, and other devices needing a compact 5 V supply. Use requires Vin within the specified range and proper input/output capacitors per the datasheet. For exact electrical specs, pinout, and package details, consult the MIC39101 datasheet.

MIC39101-5.0YM is Microchip/Micrel fixed 5 V LDO. There is no guaranteed drop‑in; check pinout/package when replacing. Functionally similar 5.0 V LDOs include:
- LM1117-5.0
- AMS1117-5.0
- LD1117V50 (ST)
- NCP1117-5.0 (ON Semiconductor)

Always verify pinout, dropout, quiescent current, and package compatibility.

Concise features of MIC39101-5.0YM (5.0 V reset supervisor):
- 5.0 V threshold voltage detector for microprocessor reset
- Power-on reset: asserts reset until Vcc is stable
- Manual reset input for external forcing of reset
- Reset output suitable for directly driving MCU reset lines (TTL/CMOS compatible)
- Very low quiescent current (suitable for battery-powered apps)
- Wide operating voltage and temperature ranges (industrial grade)
- Package: YM (surface-mount)
