The MIC5374/84 is a four output device with three 200mA LDOs and a Real Time Clock (RTC) 1mA LDO which is ideal for application processor support in mobile platforms. The MIC5374 provides independent control active high enables for each of the 200mA LDOs with an additional always-on RTC LDO. The MIC5384 provides active low enables.
The MIC5374/84 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 MIC5374/84 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 MIC5374/84 operates with very small ceramic output capacitors to reduce board space and component cost. It is available in various fixed output voltages. The MIC5374/84 has a junction temperature range from -40°C to +125°C.
