XC6901 Series
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 (C
quickly returns to the V
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.

■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 –V
voltage at the –V
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 -V
charge CL capacitor can be reduced and it makes the VIN stable. Soft-start time (tSS) is optimized internally.

＜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 –V
pin and GND pin. The minimized short-circuit current is maintained even if the –V
OUT
pin voltage is pulled up toward
OUT
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,-V
pin voltage goes into GND level by R1,R2 and CL discharge resistance(R
OUT
DCHG
).

＜CL High Speed Discharge＞
The XC6901D type is capable of high-speed discharge of the charge that collects on the output capacitor (C
accomplished by the P-channel MOSFET and C
discharge resistance connected between the -V
L
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.

discharge time is determined by this CL discharge resistance and CL. Letting the time constant of the CL discharge
L
and CL be τ (τ = C × R), the output voltage after discharge by the P-channel MOSFET can be obtained from

1) For temporary, transitional voltage drop or voltage rising phenomenon.
The IC is liable to malfunction should the ratings be exceeded.

● SOT-25 Power Dissipation
Power dissipation data for the SOT-25 is shown in this page.
The value of power dissipation varies with the mount board conditions.
Please use this data as one of reference data taken in the described condition.
1. Measurement Condition (Reference data)
Condition: Mount on a board
Ambient: Natural convection
Soldering: Lead (Pb) free
