General Description
The MIC5319 is a high performance, 500 mA LDO
regulator, with high PSRR and very low noise, with low
ground current.
Ideal for battery-operated applications, the MIC5319
features 1% accuracy, very low dropout voltage
(typically 200 mV @ 500 mA), and low ground current
at light load (typically 90 µA). Equipped with a
logic-compatible enable pin, the MIC5319 can be set
into a zero-off-mode current state, typically drawing
only 0.5 µA current when disabled.
The MIC5319 is a µCap design operating with very
small ceramic output capacitors for stability, thereby
reducing required board space and component cost.
The MIC5319 is available in fixed-output voltages and
adjustable output versions in the compact 2 mm x
2 mm DFN lead-less package or the thin SOT23-5
package.
