! GENERAL DESCRIPTION
! FEATURES
The XC6401 series are highly accurate, Dual, low noise, CMOS LDO
voltage regulators. Performance features of the series includes low
output noise, high ripple rejection ratio, low dropout and very fast

turn-on times.
Operating Voltage Range
The XC6401 includes a reference voltage source, error amplifiers,
driver transistors, current limiters and phase compensators internally.
The XC6401’s current limiters' foldback circuit also operates as a

short protect for the output current limiter.
The output voltage for each regulator is set independently by laser
trimming. Voltages are selectable in 50mV steps within a range of
Low Power Consumption
0.8V to 5.0V. The XC6401 series is also fully compatible with low
ESR ceramic capacitors, reducing cost and improving output stability.
This high level of output stability is maintained even during frequent

independently, resulting in greatly reduced power consumption.
The XC6401 series is available in the SOT-26W or USP-6B ‘chip-
scale’ package.
