Duwawlw.LDaDtaOSheRet4eU.gcoumlator (ch1=300mA, ch2=100mA) with ON/OFF Switch
ETR0338-003
GENERAL DESCRIPTION
The XC6419 series is a dual CMOS LDO regulator. The series features high accuracy, low output noise, high
ripple rejection and low dropout and consists of a voltage reference, error amplifier, driver transistor, current limiter,
thermal shutdown circuit and phase compensation circuit. Each output voltage is set independently by laser
trimming and selectable in 0.05V increments within a range of 0.8 to 5.0V.
The EN function turns each output of the two regulators off independently. In this state, the electric charge at the
output capacitor (CL) is discharged via the internal auto-discharge switch, and as a result the VOUT voltage quickly
returns to the VSS level. The output stabilization capacitor (CL) is also compatible with low ESR ceramic
capacitors. The high level of output stability is maintained even during frequent load fluctuations, due to the
excellent transient response performance. VR1 and VR2 are completely isolated so that a cross talk during load
fluctuations is minimized.

CIRCUITS
NOTE:
*1: Unless otherwise stated, VIN=VOUT (T) +1.0V, VEN1=0V.
*2: VOUT (E) is actual output voltage (refer to the voltage table)
(ie. The output voltage when “VOUT (T) +1.0V” is provided at the VIN pin while maintaining a certain IOUT value.
*3: Characteristics of the actual VOUT (E) by nominal output voltage is shown in the voltage table
*4: VOUT (T) is nominal output voltage
*5: Vdif = VIN1(*7) -VOUT3(*6)
*6: VOUT3 is a voltage equal to 98% of the output voltage whenever an amply stabilized IOUT{VOUT(T)+1.0V} is input.
*7: VIN1 is the input voltage when VOUT3 appears while input voltage is gradually decreased.
*8: For XC6419 xB/xD series only.
XC6419 xA /xC series discharge with only Rx1 and Rx2 resistors as shown in the BLOCK DIAGRAMS.
