■OPERATIONAL EXPLANATION
<Low ESR Capacitor>
<Output Voltage Regulator Control>
<Current Limiter, Short-Circuit Protection>
<CE Pin>
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.

We also suggest an input capacitor (C
stabilize input power source.
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.
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
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
