L6401 Series
DESCRIPTION
The L6401 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 L6401 includes a reference voltage source, error amplifiers, driver transistors, current limiters
and phase compensators internally. The L6401’s current limiter’s 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 1.3V to 5.0V.
The EN function allows the output of each regulator to be turned off independently, resulting in
greatly reduced power consumption. The L6401 series is available in the SOT-26 and USP-6B.
