Description
The PT7M8401 series are highly accurate, dual, low
dropout voltage regulators with low noise, high ripple
rejection and low current consumption.
The PT7M8401 includes a reference voltage source, error
amplifiers, driver transistors, individual enable inputs,
current limit protections, short circuit protections and
internal phase compensators.
The output voltage for each regulator is set by factory
trimming within a range of 1.2V to 4.5V in 100mV step.
The PT7M8401 series are stable with low ESR ceramic
capacitors. The PT7M8401 series are available in the
SOT23-6L packages.
