XC6415 Series
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
level. The output stabilization capacitor (C
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.
■APPLICATIONS
● Mobile phones
● Cordless phones, Wireless communication equipment
● Portable game consoles
● Digital still cameras, Digital video cameras
● Portable audio equipment
● PDAs

■OPERATIONAL DESCRIPTION
<Output Voltage Control>
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 V
the V
OUT 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>
XC6415B, D, F, H series can quickly discharge the electric charge at the output capacitor (C
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 V
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
L) as τ(τ=C x R), the output voltage after discharge via the N channel transistor is calculated by the following formulas.

■NOTES ON USE

τ: C
high-speed discharge function can be set by each regulator.
L
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 V
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.
. Please use this IC within the stated absolute maximum ratings. The IC is liable to malfunction should the ratings be
1
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.
