OPERATIONAL EXPLANATION
<Output Voltage Regulator Control>
The voltage, divided by resistors R1 & R2, which are connected to the V
OUT
pin is compared with the internal reference
voltage by the error amplifier. The P-channel MOSFET, which is connected to the V
OUT
pin, is then driven by the
subsequent output signal. The output voltage at the V
OUT
pin is controlled & stabilized by negative feedback. The
constant current limit circuit and short circuit protection operate in relation to the level of output current.
<Low ESR Capacitor>
With the XC6210 series regulator, a stable output voltage is achievable even if low ESR capacitors are used, as a phase
compensation circuit is built into the regulator. In order to ensure the effectiveness of the phase compensation, we
suggest that an output capacitor (C
L
) be connected as close as possible, between the output pin (V
OUT
) and the V
SS
pin.
Please use an output capacitor (C
L
) with a capacitance, based on the chart below. We also suggest an input capacitor
(CIN) of 1
μ
F: this should be connected between V
IN
and V
SS
in order to stabilize input power source.
Output Capacitor Corresponding Chart
<Current Limiter, Short-Circuit Protection>
The XC6210 series regulator offers a combination of current limit and short circuit protection by means of a built-in fixed
current limiter circuit and a foldback circuit. When the load current reaches the current limit level, the fixed current
limiter circuit operates and output voltage drops. As a result of this drop in output voltage, the foldback circuit operates,
the output voltage drops further and output current decreases. When the output pin is shorted, a current of about 50mA
flows.
<CE Pin>
The IC's internal regulator circuitry can be shut down via the signal from the CE pin with the XC6210 series. In
shutdown mode, output at the V
OUT
pin will be pulled down to the VSS level via R1 & R2. Options are available for the
CE pin logic (See the product classification). Note that as the XC6210B types are 'High Active / No Pull-Down',
operations will become unstable with the CE pin open. Although the CE pin is equal to an inverter input with CMOS
hysteresis, with either the pull-up or pull-down options, the CE pin input current will increase when the IC is in operation.
We suggest that you use this IC with either a V
IN
voltage or a V
SS
voltage input at the CE pin. If this IC is used with the
correct specifications for the CE pin, the IC will operate normally. However, supply current may increase as a result of
through current in the IC's internal circuitry if a voltage other than V
IN
or V
SS
is applied.

NOTES ON USE
1. 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 strengthen V
IN
and V
SS
wiring in particular.
3. Please wire the input capacitor (C
IN
) and the output capacitor (C
L
) as close to the IC as possible. Should rapid input
fluctuation or load fluctuation occur, please increase the capacitor value such as C
IN
or C
L
to stabilize the operation.
