DESCRIPTION
The MP8801 is a low-noise, low-dropout linear
regulator. It operates from a 2.7V to 6.5V input
voltage and regulates the output voltage with
2% accuracy at 2.5V, 2.85V or 3.3V. The
internally set output voltage may be overridden
with an external resistor divider from 1.25V to
5V.
The MP8801 can supply up to 150mA of load
current. The MP8801 features thermal overload
protection and is available in a 5-pin TSOT23-5
package.
