Micrel MIC5528 500mA High-Performance LDO

Micrel MIC5528 500mA High-Performance LDO

Micrel's MIC5528 500mA High-Performance LDO is a low-power, µCap, 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 38µA of operating current. This high-performance LDO is a µCap design in a thermally enhanced 1.2mmx1.2mm extra thin (0.4mm 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 (260mV @ 500mA), and can regulate output voltage 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.
