MP20041 Dual, Ultra Low Noise, High PSRR 300mA Linear Regulator The Future of Analog IC Technology DESCRIPTION FEATURES Wide Operating Voltage Ranges: 2.5V to 6V The MP20041 is a dual-channel, micropower, Two LDOs in a 2mmx2mm TQFN8 Package ultra low noise, low dropout and high PSRR Up to 300mA Output Current (Per Channel) linear regulator. The output voltage of MP20041 ranges from 1.2V to 3.6V in 100mV increments Dual Enable Pins Control Each Output and 1% accuracy by operating from a +2.5V to 72dB PSRR at 10kHz +6.0V input. The MP20041 can supply up to 11 VRMS Ultra Low Noise Output with No 300mA of load current at each channel. Noise Bypass Capacitor Required 73mV Dropout at 100mA Load The MP20041 uses an internal PMOS as the Very Fast Line/Load Transient Responses pass element, which consumes 114 A supply with Small Input/Output Capacitor current (both LDOs on) at no load condition. Current Limit and Thermal Protection The EN1 and EN2 pins control each output respectively. When both channels shutdown APPLICATIONS simultaneously, the chip will be turned off and Cellular Phones consume nearly zero operation current which is Battery-powered Equipment suitable for battery-power devices. The Laptop, Notebook, and Palmtop Computers MP20041 features current limit and over Hand-held Equipment temperature protection. Wireless LAN It is available in a 2mm x 2mm TQFN8 package. All MPS parts are lead-free, halogen free, and adhere to the RoHS directive. For MPS green status, please visit MPS website under Quality Assurance.
