ETR0332-007

Dual LDO Regulator with ON/OFF Switch

■GENERAL DESCRIPTION

The XC6415 series is a highly accurate, CMOS Dual LDO voltage regulator. Performance features include low output noise,

high ripple rejection rate, and low dropout. Extremely dense power supply circuit can be organized with a 2 channeled high

speed voltage regulator in low ON resistance which is built-in to an ultra small USP-6C package. The output voltage for each

regulator is set independently by laser trimming and selectable in 0.05V increments within a range of 0.8 to 5.0V. The EN

function allows the output of each regulator to be turned off independently. In this state, the electric charge at the output

capacitor (C_L) will be discharged via the internal auto-discharge switch, and as a result the V_OUTpin quickly returns to the V_SS

level. 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. Because

regulator 1 and 2 are completely isolated, a cross talk between each channel, which causes a problem during load fluctuations,

can be greatly reduced.

*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, if should be connected to the V_SS(No. 4) pin.

■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 which is 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.

< XC6415BB Series >

XC6415B, D, F, H series can quickly discharge the electric charge at the output capacitor (CL), when a low signal to the EN

pin, which enables a whole IC circuit put into OFF state, is inputted via the N-channel transistor located between the VOUT

pin and the VSS pin (cf. BLOCK DIAGRAM). The C_Ldischarge resistance is set to 550Ω when V_INis 6.0V (TYP.) and V_OUT

is 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 formulas.

V = VOUT x e ^–t/

,

or ｔ=τln（ VOUT_(E)/ V ）

τ

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

τ: CL auto-discharge resistance R×Output capacitor (CL) value C)

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

The XC6415 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, a current of about 20mA flows.

The IC's internal circuitry can be shutdown via the signal from the EN pin with the XC6415 series. In shutdown mode,

output at the VOUT pin will be pulled down to the VSS level via Rx1 & Rx2. However, as for the XC6415B, D, F, H 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 EN pin is CMOS input, but in case the EN

pin with pulled down resistor, the EN input current will be increase when the IC operates. Also, in case of the EN pin

without pulled down resistor, the output voltage becomes unstable when the EN pin is left 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 voltage is input.

■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.
