HIGH SPEED LOW DROPOUT MIDDLE CURRENT VOLTAGE REGULATORS
Dual 300mA High Speed Low Dropout CMOS Voltage Regulators
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.
