General Description
The MIC5373/83 is a triple output device with three 200mA
LDOs which is ideal for application processor support in
mobile platforms. The MIC5373 provides independent
control active high enables for each of the 200mA LDOs.
The MIC5383 provides active low enables. Both the
MIC5373 and MIC5383 are available in the tiny 2.5mm x
2.5mm Thin MLF® package.
The MIC5373/83 is designed for high input ripple rejection
(high PSRR) and provides low output noise making it ideal
for powering sensitive RF circuitry such as GPS, WiFi and
Bluetooth applications. The MIC5373/83 also incorporates
a power-on-reset (POR) supervisor with adjustable delay
time set by an external capacitor, and an independent
input pin to monitor any voltage level. Once high, the POR
output can be asserted low again by enabling the manual
reset (MR) pin. When the MR pin is restored low, the POR
output will re-time the delay set by the external delay
capacitor.
The MIC5373/83 operates with very small ceramic output
capacitors to reduce board space and component cost. It
is available in various fixed output voltages. The
MIC5373/83 has a junction temperature range from −40°C
to 125°C.
