Overview

PT7M8216 is a high accurate, low dropout voltage regulator with low noise, high ripple rejection and low current consumption.

PT7M8216 includes a reference voltage source, an error amplifier, a driver transistor, a current limit protection, a thermal protection and an internal phase compensator.

The output voltage for the regulator is set by factory trimming within a range of 0.9V to 3.3V in 100mV step includes 2.85V. PT7M8216 is stable with low ESR ceramic capacitors.

PT7M8216 is available in a 1mm×1mm UDFN-4L and 0.8mm×0.8mm UDFN-4L packages. It operates over a temperature range of -40 to +85°C.
