MAX38911/MAX38912 11µVRMS Low-Noise, 500mA LDO Linear Regulators with Low-Power Mode
Absolute Maximum Ratings
IN, OUT, EN, FB, OUTS to GND .. -0.3V to 6V Operating Junction Temperature Range ... -40˚C to +125˚C MODE, BYP, POK to GND ... -0.3V to 6V Maximum Junction Temperature ... +150˚C Output Short-Circuit Duration .. Continuous Storage Temperature Range ... -65˚C to +150˚C Continuous Power Dissipation (T Lead Temperature (Soldering, 10s) .. +300˚C A = +70°C) ... WLP (derate 10.51mW/°C above +70°C) ... 840mW Soldering Temperature (Reflow) ... +260˚C TDFN (derate 11.7mW/C above +70C) .. 937.9mW Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
