NJM78LR05BD/CD/BL/CL

is the NRND product.

■ APPLICATION CIRCUIT

td [ms] = 100×Cd [μF]

Note 1 : When the capacitance Cd is too large, the actual delay time is shorter than the calculated result because an

electrical charge of Cd is discharged incompletely.

Solution of above problem :

(1) Connect SBD between output terminal and Cd terminal. Please refer to the fallowing circuit.

(2) Select larger capacitance, CIN than Cd.
