Description
The PT7M8208 series are highly accurate, low dropout
voltage regulators with low noise, high ripple rejection
and low current consumption.
The PT7M8208 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 PT7M8208 series are stable with
low ESR ceramic capacitors.
