MIC5528-3.3YMT-TR

The MIC5528 is a low-power, ACap, low dropout regulator designed for optimal performance in a very small footprint. It is capable of sourcing up to 500 mA of output current while only drawing 38 μA of operating current. This high performance LDO is a UCap design in a thermally enhanced 1.2 mm×1.2 mm extra thin (0.4 mm height) DFN package. It operates with small ceramic output capacitor for stability, thereby reducing required board space. Ideal for battery-operated applications, the MIC5528 offers ±2% accuracy, extremely low dropout voltage (260 mV @ 500 mA), and can regulate output voltages down to 1.0 V. Equipped with a TTL logic-compatible enable pin, the MIC5528 can be put into a zero-off-mode current state, drawing no current when disabled. The MIC5528 is a UCap design, operating with very small ceramic output capacitors for stability, reducing required board space and component cost for space-critical applications. The MIC5528 has an operating junction temperature range of -40°C to 125°C.
