(*3)
The output voltage excludes under 3.8V.
(*4): These parameter are guaranteed with only -40°C and +125°C.
The above specification is a common specification for all output voltages.
Therefore, it may be different from the individual specification for a specific output voltage.
* These parameters are tested by Pulse Measurement.

State of control pin:
•“H”→
output is enabled.
•“L”
or “open”
→
output is disabled.
*In the case of using a resistance "R" between V
IN
and control.
If this resistor is inserted, it can reduce the control current when the control voltage is high.
The applied voltage to control pin should set to consider voltage drop through the resistor “R” and the minimum
control voltage for ON-state.
The V
CONT (ON)
and I
CONT
have temperature dependence as shown in the "Control Current vs. Temperature" and "
Control Voltage vs. Temperature" characteristics. Therefore, the resistance "R" should be selected to consider the
temperature characteristics.
