XC6901 Series
ETR03043-007
200mA Negative Voltage Regulator with ON/OFF Control
■GENERAL DESCRIPTION
The XC6901 Series is a negative voltage CMOS regulator which includes a reference voltage source, error amplifier, driver
transistor, current limiter and phase compensator.
The CE function enables the circuit to be in stand-by mode by inputting low level signal. In the stand-by mode, the electric
charge at the output capacitor (CL) will be discharged via the internal auto-discharge switch and as a result the -VOUT pin
quickly returns to the VSS level.
The over current protection circuit will operate when the output current reaches limit current. The thermal shutdown circuit will
operate when the junction temperature reaches limit temperature.

■PIN CONFIGURATION
* The dissipation pad for the USP-6C package should be solder-plated in recommended mount pattern and metal masking to enhance
mounting strength and heat release. If the pad needs to be connected to other pins, it should be connected to the -VIN (No. 3) pin.

*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.

■OPERATIONAL EXPLANATION
The voltage divided by resisters 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.
＜Soft Start Function＞
XC6901 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.
Figure1：Soft Start Time and Inrush Current
＜Current Limit, Short-Circuit Protection＞
The XC6901 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.
＜Thermal Shutdown＞
The XC6901 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.
＜CE Pin＞
The XC6901 Series is able to shut down the regulator circuit using the CE pin signal. CE pin can be controlled with positive voltage due
to P-channel transistor source input (Gate is grounded). A current flow of a few micro amperes. The regulator is turned on when CE input
voltage is positive, the regulator is turned off when CE input is GND.
When CE pin is open, IC is turned OFF, due to the built-in Pull-down resistor. When the IC is turned OFF with low input voltage to the
CE pin,-VOUT pin voltage goes into GND level by R1,R2 and CL discharge resistance(RDCHG).

Series
■OPERATIONAL EXPLANATION(Continued)
＜CL High Speed Discharge＞
The XC6901D type is capable of high-speed discharge of the charge that collects on the output capacitor (CL below). This is
accomplished by the P-channel MOSFET and CL discharge resistance connected between the -VOUT and GND pins in the block
diagram, and takes place when the L-level signal (IC internal circuit shutdown signal) of the CE pin is input so that it could avoids
malfunction.
The CL discharge time is determined by this CL discharge resistance and CL. Letting the time constant of the CL discharge
resistance RDCHG and CL be τ (τ = C × R), the output voltage after discharge by the P-channel MOSFET can be obtained from
the CR discharge equation below. Please be noted that RDCHG various with supply voltage and VDS(drain-source voltage) since it
consists of P-channel MOSFET.
ｔ = τln（VOUT(E) / V）
V：Output voltage during discharge
VOUT(E)：Output voltage
t：Discharge time
τ：CL auto-discharge resistance RDCHG × CL Output capacitor value CL
＜Low ESR Capacitor＞
With the XC6901 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 for all environment conditions.

XC6901 Series
■NOTE ON USE
1) 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 enforce wiring –VIN and GND.
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.
