NOTE:
The test condition for input voltage, Unless otherwise stated, GND=0V、VIN=VOUT(T)-1.0V or -2.4V.
*1) VOUT(T): Nominal output voltage
*2) VOUT(E): Effective output voltage (see the voltage chart)
(ie.The output voltage when “VOUT(T)-1.0V” or “-2.4V”is provided at the VIN pin while maintaining a certain IOUT value.
*3）Vdif＝-{VIN1- VOUT1}
VIN1 is the input voltage when VOUT1 appears at the VOUT pin while input voltage is gradually increased
VOUT1 is the voltage equal to 98% of the normal output voltage when amply stabilized VOUT(T) -1.0V or -2.4V (the bigger absolute value one )
are input at the VIN pin.
*4) The maximum current may not be able to flow when thermal shutdown operates, it depends on power dissipation.
*5) E-1:Refer to Dropout Voltage Chart.
*6) Input voltage condition is VIN=0V → VOUT-1V with 5μs rising time.
Soft-start time tSS is defined as the time taken from the 90% rising of VIN to the 95% rising of VOUT(E).

XC6902 Series
■OPERATIONAL EXPLANATION
The voltage divided by resistors R1 and R2 is compared with the internal reference voltage based on ground by the error
amplifier.
The driver transistor tied to the -VIN 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.
XC6902 Series
＜Soft-Start Function＞
The XC6902 series includes soft-start circuit. During power start-up, the inrush current from –VIN pin to VOUT pin to charge CL
capacitor can be reduced and it makes the VIN stable. Soft-start time (tSS) is optimized internally.
Fugure1：Soft-Start Time and Inrush Current
＜Current Limiter, Short-Circuit Protection＞
The XC6902 series fold-back circuit operates as an output current limiter and a short protection circuit for the output pin. When the
output current reaches the current limit level, output voltage drops with the decrease of the output current.
There are no parasitic diode between the -VOUT pin and GND pin. The minimized short-circuit current is maintained even if the -VOUT
pin voltage is pulled up toward positive.
The XC6902 Series has an internal thermal shutdown (TSD) circuit for protection against overheating.
When the junction temperature reaches the detection temperature, the driver transistor is forcibly turned off. When the junction
temperature falls to the release temperature with the driver transistor still in the off state, the driver transistor turns on (automatic
recovery) and restarts regulator operation.

■OPERATIONAL EXPLANATION (Continued)
＜Low ESR Capacitor＞
With the XC6902 series, a stable output voltage is achievable even if used with low ESR capacitors, as a phase compensation
circuit is built-in. The output capacitor (CL) should be connected as close to VOUT pin and GND pin to obtain stable phase
compensation. Values required for the phase compensation are as the table below.
For a stable power input, please connect an input capacitor (CIN) near power supply. In order to ensure the stable phase
compensation while avoiding run-out of values, please use the capacitor (CIN, CL ) which does not depend on bias or temperature
too much. The table below shows recommended values of CIN, CL.

■NOTES ON USE
1. Please use this IC within the stated maximum ratings. For temporary, transitional voltage drop or voltage rising
phenomenon, 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 keep the resistance low for the -VIN and GND wiring in particular.
3. Please wire the CIN and CL as close to the IC as possible.
4. Capacitances of these capacitors (CIN, CL) are decreased by the influences of bias voltage and ambient
temperature. Care shall be taken for capacitor selection to ensure stability of phase compensation from the point of ESR
influence.
5. Torex places an importance on improving our products and its reliability.
However, by any possibility, we would request user fail-safe design and post-aging treatment on system or equipment.
