Note1. R is a pull-up resistance for reset terminal. 2.2kohm is recommended for the value.

Note2. C1 works for stabilizing input voltage. Recommended value is 10uF.

Note3. Co works for preventing the output voltage from oscillation. Minimum value is 10uF.

Recommended value is 47uF.

Note4. Delay time for reset is changeable by the capacitance connected to Cd terminal.

Even when no capacitor is connected, 30usec.(typ.) delay time is available.

Below shows how to set the delay time.

Delay time:Tpd(ms)=100×Cd(µF)

Example:when 0.1uF is connected to Cd terminal.

Tpd(ms)=100×0.1(µF)

=10 (ms)

Note5. Connect ON/OFF terminal and VIN when ON/OFF function is not needed.

Note6. Get the capacitors close to IC terminals in case the operation is not stabilized by the

wiring resistance between each capacitor and IC terminals.
