Device Overview

Summary

The MIC5524 is a low-power, μCap, low dropout regulator designed for optimal performance in a very-small footprint. It is capable of sourcing 500mA of output current and only draws 38μA of operating current to do so. The MIC5524 includes an auto-discharge feature on the output that is activated when the enable pin is low and it has an internal pull down resistor on the enable pin that will disable the output when the enable pin is left floating, this is ideal for applications where the control signal is floating during processor boot up.

This high-performance LDO offers fast transient response and good PSRR in a 1mm x 1mm Thin (0.4mm high) DFN package.

Ideal for battery-operated applications, the MIC5524 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 MIC5524 can be put into a zero-off-mode current state, drawing no current when disabled.

The MIC5524 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 MIC5524 has an operating junction temperature range of -40°C to 125°C.
