*1: Operation start voltage becomes 16 to 18 V.

*2: Pulse noise does not include it.

The capacitance of C3 should be 10µF, since an excessively small value will result in malfunction. The activation time is defined as : t(s)=R2*C3 ln[1-17/(VI-30µA*R2)], where VI is

The resistance of R2 should be 1.5MΩ, since an excessively small value will result in malfunction.

Electrical Characteristics

Sample Application Circuit

An excessively large capacitance at C2 may cause the output to become inactive. Therefore, a capacitance between 500 to 2200µF is recommended, with a rise time of 10us or

less.
