MIC5528
High-Performance 500mA LDO
in Extra Thin DFN Package
General Description
The MIC5528 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 1.2mm × 1.2mm extra thin (0.4mm ht.) 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 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.
