General Description
The MIC5308 is a high performance, µCap low dropout
regulator, offering ultra-low operating current while
maintaining very fast transient response. The MIC5308
can source up to 150mA of output current and can
regulate down from a low input supply voltage to increase
system efficiency.
Ideal for battery operated applications; the MIC5308 offers
extremely low dropout voltage 45mV typically @ 150mA,
and low ground current at all load conditions (typically
23µA). The MIC5308 can also be put into a zero-off-mode
current state, drawing virtually no current when disabled.
The MIC5308 is available in fixed output voltages in the
tiny 6-pin 1.6mm x 1.6mm thin MLF
well as the 6-pin TSOT-23 for cost sensitive applications.
