MP8801 Low Dropout 150mA Linear Regulator The Future of Analog IC Technology DESCRIPTION FEATURES Low 100mV Dropout at 100mA Output The MP8801 is a low-noise, low-dropout linear 2% Accurate Output Voltage regulator. It operates from a 2.7V to 6.5V input voltage and regulates the output voltage with Fixed Output Voltage Options of 2.5V, 2.85V or 3.3V 2% accuracy at 2.5V, 2.85V or 3.3V. The internally set output voltage may be overridden Adjustable Output Voltage from 1.25V with an external resistor divider from 1.25V to to 5V using an External Resistor Divider 5V. Up to 6.5V Input Voltage High PSRR The MP8801 can supply up to 150mA of load o 70dB at 1kHz current. The MP8801 features thermal overload o 30dB at 1MHz protection and is available in a 5-pin TSOT23-5 Better Than 0.001%/mA Load package.
