XC6401Series

ETR0309_005

Dual LDO Regulators, Low ESR Cap. Compatible

■GENERAL DESCRIPTION

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.

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 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 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. The XC6401 series is available in

the SOT-26W or USP-6B, USP-6C ‘chip-scale’ package.
