OPERATIONAL EXPLANATION (Continued)
<Current Limiter, Short-Circuit Protection>
The XC6221 series’ foldback circuit operates as an output current limiter and a short protection of the output pin. When
the load current reaches the current limit level, the fixed current limiter circuit operates and output voltage drops. When
the output pin is shorted to the V
SS
level, a current of about 30mA flows.
<CE Pin>
The IC's internal circuitry can be shutdown via the signal from the CE pin with the XC6221 series. In shutdown mode,
output at the V
OUT
pin will be pulled down to the V
SS
level via R1 & R2. However, as for the XC6221B series, the C
L
auto-discharge resistor is connected in parallel to R1 and R2 while the power supply is applied to the V
IN
pin.
Therefore, time until the V
OUT
pin reaches the V
SS
level becomes short. The output voltage becomes unstable, when
the CE pin is open. If this IC is used with the correct output voltage for the CE 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
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 (C
IN
) and the output capacitor (C
L
) as close to the IC as possible.
