■OPERATIONAL EXPLANATION
■NOTES ON USE
<Low ESR Capacitors>
With the XC6209/6212 series, a stable output voltage is achievable even if used with low ESR capacitors as a phase
compensation circuit is built-in. In order to ensure the effectiveness of the phase compensation, we suggest that an
output capacitor (C
output capacitor with a capacitance value of at least 1μF. Also, please connect an input capacitor (C
between the V
Stable phase compensation may not be ensured if the capacitor runs out capacitance when depending on bias and
temperature. In case the capacitor depends on the bias and temperature, please make sure the capacitor can
ensure the actual capacitance.
<Current Limiter, Short-Circuit Protection>
The XC6209/6212 series includes a combination of a fixed current limiter circuit & a foldback circuit, which aid the
operations of the current limiter and circuit protection. 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, 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 circuitry can be shutdown via the signal from the CE pin with the XC6209/6212 series. In shutdown
mode, output at the V
is selectable (please refer to the selection guide). Note that as the standard XC6209/6212B type is ' 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’s in operation.
We suggest that you use this IC with either a VIN voltage or a VSS 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
