TOREX XC6419AB03EL

XC6419 Series
ETR0338-003
Dual LDO Regulator (ch1=300mA, ch2=100mA) with ON/OFF Switch
■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.

■PIN CONFIGURATION
*The dissipation pad for the USP-6C package
should be solder-plated in recommended mount
pattern and metal masking so as to enhance
mounting strength and heat release.
If the pad
needs to be connected to other pins, it should be
connected to the VSS (No. 4) pin.

XC6419 Series
■OPERATIONAL DESCRIPTION
The voltage divided by resistors Rx1 and Rx2 is compared with the internal reference voltage by the error amplifier. The
P-channel MOSFET connected to the VOUT pin is then driven by the subsequent output signal. The output voltage at the
VOUT pin is controlled and stabilized by a system of negative feedback. The current limit circuit and short protect circuit
operate in relation to the level of output current. Further, the IC's internal circuitry can be shutdown via the EN pin's signal.
<CL Auto-Discharge Function>
XC6419xB/Bx/xD/Dx series can quickly discharge the electric charge at the output capacitor (CL) through the N-channel
transistor located between the VOUT pin and the VSS pin (refer to the BLOCK DIAGRAM) when a low level signal is applied
to the EN pin. The CL discharge resistance is set to 550Ω when VIN is 6.0V (TYP.) and VOUT is 4.0V (TYP.). Moreover,
discharge time of the output capacitor (CL) is set by the CL auto-discharge resistance (R) and the output capacitor (CL). By
setting time constant of a CL auto-discharge resistance value [R] and an output capacitor value (CL) as τ(τ=C x R), the
output voltage after discharge via the N channel transistor is calculated by the following formulae.
–t/
V = VOUT x e τ, or ｔ = τln（VOUT (E) / V）
where
V: Output voltage after discharge, VOUT (E): Output voltage, t: Discharge time,
τ: CL auto-discharge resistance RDCHG×CL capacitance C
CL high-speed discharge function can be set by each regulator.
<Current Limiter, Short-Circuit Protection>
The XC6419 series includes a fold-back circuit, which aid the operations of the current limiter and circuit protection. When
the load current reaches the current limit level, the fold-back circuit operates and output voltage drops. As a result of this
drop in output voltage, output current also decreases. When the output pin is shorted, the output current flows go down to
30mA / ch1 and 15mA/ch2 （TYP.）.
<EN Pin>
Each regulator can be shut-downed via the signal from the EN pin with the XC6419 series. In shutdown mode, output at
the VOUT pin will be pulled down to the VSS level via Rx1 & Rx2. However, as for the XC6419xB/Bx/xD/Dx series, the CL
auto-discharge resistor is connected in parallel to Rx1 and Rx2 while the power supply is applied to the VIN pin.
Therefore, time until the VOUT pin reaches the VSS level becomes short. The output voltage becomes unstable, when the
EN pin is open. If this IC is used with the correct output voltage for the EN pin, the logic is fixed and the IC will operate
normally. However, supply current may increase as a result of through current in the IC's internal circuitry when medium

■OPERATIONAL DESCRIPTION (Continued)
<Input and Output Capacitor>
The XC6419 needs an output capacitor CL for phase compensation. The requested capacitance values are described in the
table below. The device may go into unstable operation when the output capacitance reduction happens as a result of bias or
temperature drift. Please choose a capacitor with less influence from temperature and bias. Also, please place 1.0μF input
capacitor CIN between VIN and VSS pins for stabilizing input supply voltage.

■NOTES ON USE
1. Please use this IC within the stated absolute maximum ratings. The IC is liable to malfunction should the ratings be
exceeded.
2. Where wiring impedance is high, operations may become unstable due to noise and/or phase lag depending on output
current. Please wire the input capacitor CIN and the output capacitor CL as close to the IC as possible.
