General Description
The MIC5396, MIC5397, MIC5398, and MIC5399 are
advanced dual LDOs ideal for powering general
purpose portable devices. The MIC5396/7/8/9 provide
two high performance, independent 300 mA LDOs in a
single package. This makes it possible to improve
system efficiency by providing two independent supply
inputs that can be optimized for each individual LDO.
The MIC5396/7/8/9 also feature a wide output voltage
range down to 1.0V.
Its full feature set and low dropout voltage make it ideal
for battery-powered applications. The MIC5396/7/8/9
offer 2% accuracy, low dropout voltage (160 mV at
300 mA), and low ground current (typically 42 μA per
LDO at full load). The MIC5396/7/8/9 can also be put
into a zero off mode current state, drawing virtually no
current when disabled.
When the MIC5397 or MIC5399 are disabled, an
internal resistive load is automatically applied to the
output to discharge the output capacitor. In addition,
the MIC5398 and MIC5399 offer an internal enable
pull-down resistor to ensure that the output is disabled
when the enable is in tri-state mode. These LDOs also
offer fast transient response and high PSRR while
consuming a minimum operating current. The family is
available in a tiny 8-lead, 1.6 mm x 1.2 mm leadless
Extra Thin DFN package.
