Description
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 PT7M8202 series are stable with
low ESR ceramic capacitors.The PT7M8205 series are
highly accurate, low dropout voltage regulators with low
noise, high ripple rejection and low current consumption.
The PT7M8205 includes a reference voltage source, an
error amplifier, a driver transistor, a current limit
protection, a thermal protection and an internal phase
compensator.
