MIC5383

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.
