Description

The MIC5528 is a low-power, ?Cap, low-dropout regulator designed for optimal performance in a very small footprint. It is capable of sourcing up to 500mA of output current while only drawing 38?A of operating current. This high-performance LDO is a μCap design in a thermally enhanced 1.2mm x 1.2mm extra thin (0.4mm ht.) DFN package. It operates with a small ceramic output capacitor for stability, thereby reducing the required board space.
Ideal for battery-operated applications, the MIC5528 offers ?2% accuracy, extremely low dropout voltage (260mV @ 500mA), and can regulate output voltages down to 1.0V. 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 μCap 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.
