Description
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.

Note:
Stresses greater than those listed under MAXIMUM
RATINGS may cause permanent damage to the
device. This is a stress rating only and functional
operation of the device at these or any other
conditions above those indicated in the operational
sections of this specification is not implied.
Exposure to absolute maximum rating conditions
for extended periods may affect reliability.
