MIC5524

High-Performance 500mA LDO

in Thin DFN Package

General Description

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 × 1mm Thin (0.4mm ht.) 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.
