General Description

The MIC5219 is an efficient linear voltage regulator

with high peak output current capability, very low

dropout voltage, and better than 1% output voltage

accuracy. Dropout is typically 10 mV at light loads and

less than 500 mV at full load.

The MIC5219 is designed to provide a peak output

current for start-up conditions where higher inrush

current is demanded. It features a 500 mA peak output

rating. Continuous output current is limited only by

package and layout.

The MIC5219 can be enabled or shut down by a

CMOS- or TTL-compatible signal. When disabled,

power consumption drops nearly to zero. Dropout

ground current is minimized to help prolong battery life.

Other key features include reversed-battery protection,

current limiting, overtemperature shutdown, and low

noise performance with an ultra-low noise option.

The MIC5219 is available in adjustable or fixed output

voltages in the space-saving 6-pin (2 mm × 2 mm)

VDFN, 6-pin (2 mm × 2 mm) Thin DFN, SOT23-5, and

8-pin power MSOP packages. For higher power

requirements see the MIC5209 or MIC5237.

Applications
