Description
The PT7M8206 series are highly accurate, low dropout
voltage regulators with low noise, high ripple rejection
and low current consumption.
The PT7M8206 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 1.2V to 3.3V in 100mV step
includes 2.85V. The PT7M8206 series are stable with
low ESR ceramic capacitors.

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 condi-
tions above those indicated in the operational sec-
tions of this specification is not implied. Exposure
to absolute maximum rating conditions for extended
periods may affect reliability.
