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.
