... FPGA. The MIC47050 consumes little quiescent current and therefore can be used for driving the core voltages of mobile processors, post regulating a core DC/DC converter in any processor. The MIC47050 is available in fixed and adjustable output voltages in the tiny 2mm x 2mm MLF packages with an operating junction temperature range of 40C to 125C. ...

... See the Typical Characteristic section for examples of load transient response. Output Capacitor The MIC47050 requires an output capacitor of 1µF or greater to maintain stability. The design is optimized for use with low-ESR ceramic chip capacitors. High-ESR capacitors may cause high-frequency oscillation. The output capacitor can be increased, but performance has been optimized for a 1µ ...

... A 20°C hysteresis is built in to allow the device to cool before turning back on. Thermal Considerations The MIC47050 is designed to provide 0.5A of continuous current in a very small package. Maximum ambient operating temperature can be calculated based on the output current and the voltage drop across the part. ...
