XC6419Series

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 (C_L) is discharged via the internal auto-discharge switch, and as a result the V_OUTvoltage quickly

returns to the V_SSlevel. The output stabilization capacitor (C_L) 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 V_SS(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.

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 C_Ldischarge resistance is set to 550Ω when V_INis 6.0V (TYP.) and V_OUTis 4.0V (TYP.). Moreover,

discharge time of the output capacitor (CL) is set by the C_Lauto-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.

V = VOUT x e ^–t/

,

or ｔ = τln（VOUT (E) / V）

τ

where

V: Output voltage after discharge, VOUT (E): Output voltage, t: Discharge time,

τ: CL auto-discharge resistance R_DCHG×CL capacitance C

C_Lhigh-speed discharge function can be set by each regulator.

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.）.

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)

The XC6419 needs an output capacitor C_Lfor 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 C_INbetween V_INand V_SSpins for stabilizing input supply voltage.

1.2V～5.0V

C_L≧1.0μF

■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.

Soldering: Lead (Pb) free

Board:

Dimensions 40 x 40 mm (1600 mm²in one side)

Copper (Cu) traces occupy 50% of the board area

In top and back faces

Package heat-sink is tied to the copper traces

Glass Epoxy (FR-4)

Material:

Thickness: 1.6 mm

Through-hole: 4 x 0.8 Diameter

Evaluation Board (Unit: mm)
