*When using together with Positive output regulator
Positive REG

Negative REG
Vout
Load
When using positive output regulator together with this
device, sometimes the voltage may not be outputted. To
solve this problem, please connect Schottkey diode
between GND and output, or change the timing of On/Off.
*When not using ON/OFF function
Please connect the Cont terminal to GND.
*Notes when evaluating with output terminal is
connected to GND(short-circuit)
The output terminal becomes plus potential by the
resonance of Cout (C element) connected to output and
the short-circuit line (L element). When the output
terminal becomes positive, parasitism Tr is caused inside
the IC. The latch-up phenomenon occurs and in the worst
case, IC may be damaged.(f0=1 / 2π√(L C))
This resonance appears remarkably when using a ceramic
capacitor with small ESR, etc. This can be solved by
connecting 2
resistance in series. As a result, the
latch-up phenomenon in IC can be prevented.
Generally, tantalum capacitor has enough ESR value and
the influence of the resonance decreases.
