The MIC5249-3.3YMM-TR is a 300mA, fixed 3.3V output linear voltage regulator from Microchip Technology. Designed for noise-critical applications, it features a low dropout voltage of typically 340mV at 300mA and high PSRR of 65dB at 120Hz. The regulator offers ±1.0% initial accuracy and ±3.0% accuracy over temperature.
Key features include power-on reset (POR) with adjustable delay, a logic-compatible enable pin, current limit, and thermal shutdown protection. It is stable with ceramic output capacitors and designed to work with low-ESR ceramic capacitors, making it suitable for space-constrained battery-powered devices.
The MIC5249-3.3YMM-TR is supplied in a compact 8-MSOP package, suitable for surface mounting. Its applications include cellular phones, PDAs, and fiber optic modules where efficient and precise voltage regulation is required.
