MP20249DC-MC-LF-Z

MP20249DC-MC-LF-Z Monolithic Power Systems, IC REG LDO 1.2V/1.85V 0.2A WLCSPThe MP20249DC-MC-LF-Z is a dual-channel, ultra-low noise, low dropout and high PSRR linear regulator. Fixed output voltage options are available  between 1.2V to 3.3V with 1% accuracy by operating from a +2.3V to +6.0V input. It is designed to deliver up to 200mA of load current at each channel. Dropout voltage is only 75mV at full  load.  The  MP20249  uses  internal  PMOSFETS as pass elements, which consume 125μA supply current (both LDOs on) at no load condition. With new innovative design techniques, the MP20249DC-MC-LF-Z can achieve an output voltage noise as low as 16μVRMS without using a bypass capacitor at each channel. The MP20249DC-MC-LF-Z is designed and optimized to work with small-value, low-cost ceramic capacitors, making it ideal for applications with space-constraints. It typically requires only 1μF of output capacitance for stability with any load at each channel. The EN1 and EN2 pins control each output respectively. When both channels shutdown simultaneously, the chip is turned off and consumes nearly zero operation current, which is suitable for battery-power devices. The MP20249DC-MC-LF-Z features current limit and over-temperature protection.The MP20249DC-MC-LF-Z also has an output discharge function that controls the quick discharging of the output capacitor. It is available in a miniature 6-ball WLCSP package.Applications• Cellular Mobile Phones • Digital Cameras • Handheld and Battery-powered Equipment • Wireless LAN • Post DC-to-DC Regulation 9icnet Electronics is an authorized Monolithic Power Systems distributor.
