MIC5239YM

MIC5239YM is Microchip/Micrel’s 1-A low-dropout (LDO) linear regulator with an enable pin. It provides a stable output from a higher input with low dropout and fast transient response. Available in YM-packaged variants (SOT-23-5) with fixed or adjustable outputs, it includes protection features such as enable control, current limit, and thermal shutdown. Typical uses are battery-powered and portable devices, powering microcontrollers, sensors, and other circuitry that require a clean, regulated voltage.
How to use: place a suitable input capacitor close to the regulator, and an output capacitor as recommended by the datasheet for stability; use the EN pin to enable/disable; ensure the input/output conditions stay within the specified limits and account for thermal and current limits.
For exact output voltages, package details, quiescent current, and protection specs, consult the MIC5239YM datasheet.

MIC5239YM is a small, low-dropout LDO regulator. Key features commonly cited:
- Ultra-low dropout LDO regulator
- Fixed and adjustable output options in YM (small SOT-23-5/SC-70-5) package
- Output current capability up to about 150 mA
- Very low quiescent current (ideal for battery-powered apps)
- Low output noise and good Power Supply Rejection Ratio (PSRR)
- Enable (EN) pin for easy shutdown
- Built-in protections: overcurrent/short-circuit protection, thermal shutdown
- Reverse/current protection options to safeguard the device and load
- Suitable for portable and compact designs requiring a small footprint
Note: exact output voltages, input range, and current capability vary by variant. Check the specific MIC5239YM datasheet for precise electrical specs and available fixed/adjustable options.

MIC5239YM is a 5-pin SOT-23-5 low-dropout regulator (LDO). It provides a regulated output voltage from an input supply and includes an enable (EN) pin to turn the regulator on/off. Pins include VIN, VOUT, GND, EN, and a fifth pin that is ADJ for adjustable variants or NC for fixed-output versions. In short: 5 pins; LDO regulator with enable (fixed or adjustable output depending on variant).
