Description
The PT7M8411 series are highly accurate, dual, low
noise, CMOS LDO voltage regulators. Performance
features of the series include low output noise, high
ripple rejection ratio, low dropout and very fast turn-on
times. The PT7M8411 includes a reference voltage
source, error amplifiers, driver transistors, current
limiters and phase compensators internally. The output
voltage for each regulator is set independently by
trimming. Voltages are selectable in 100mV steps within
a range of 1.2V to 3.3V includes 2.85V. The PT7M8411
series are also fully compatible with low ceramic
capacitors, reducing cost and improving output stability.
This high level of output stability is maintained even
during frequent load fluctuations, due to the excellent
transient response performance and high PSRR achieved
across a broad range of frequencies. The EN function
allows the output of each regulator to be turned off
independently, resulting in greatly reduced power
consumption.
