≤1.8V version : Co=4.7F
Connect control terminal to VIN terminal
2 In use of ON/OFF CONTROL:

1.8V<Vo
≤ 2.6V version : Co=2.2F(ceramic)

≤1.8V version : Co=4.7F(ceramic)
State of control terminal:
“H”→ output is enabled.
“L” or “open” → output is disabled.
%Noise bypass Capacitance Cp
Noise bypass capacitance Cp reduces noise generated by band-gap reference circuit. Noise level and ripple
rejection will be improved when larger Cp is used. Use of smaller Cp value may cause oscillation.
Use the Cp value of 0.01
F greater to avoid the problem.
%In the case of using a resistance "R" between VIN and control.
The current flow into the control terminal while the IC is ON state (ICONT) can be reduced when a pull up resistance
"R" is inserted between VIN and the control terminal.
The minimum control voltage for ON state (VCONT(ON)) is increased due to the voltage drop caused by ICONT and the
resistance "R". The ICONT is temperature dependence as shown in the "Control Current vs. Temperature"
characteristics. Therefore, the resistance "R" should be carefully selected to ensure the control voltage exceeds the
VCONT (ON) over the required temperature range.
