XC6215 Series
■ OPERATIONAL EXPLANATION
● XC6215B Series (As for the XC6215P Series, with no CE pin)
<Output Voltage Control>
The voltage divided by resistors R1 & R2 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 and stabilized by a system of negative feedback. The current limit circuit and short protect circuit operate in relation
to the level of output current. Further, the IC's internal circuitry can be operated or shutdown via the CE pin's signal.

<Short Protection Circuit>
The XC6215 series’ regulator offers circuit protection by means of a built-in 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 circuitry can be operated or shutdown via the signal from the CE pin with the XC6215B series. In shutdown
mode, output at the V OUT pin will be pulled down to the V SS level via R1 & R2. Note that the XC6215 series’ regulator is “High
Active/No Pull-Down”, operations will become unstable with the CE pin open. 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 operational 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.
■ 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.
3. As for the XC6215 series, internally achieved phase compensation makes a stable operation of the IC possible even when
there is no output capacitor (C L ). In order to stabilize the V IN ’s voltage level, we recommend that an input capacitor (C IN ) of
about 0.1 to 1.0 μ F be connected between the V IN pin and the V SS pin. Moreover, during transient response, so as to prevent
an undershoot or overshoot, we recommend that the output capacitor (C L ) of about 0.1 to1.0 μ F be connected between the
V OUT pin and the V SS pin. However, please wire the input capacitor (C IN ) and the output capacitor (C L ) as close to the IC as
possible.
