What is the Quiescent current (the CONTROL terminal voltage (Vcont) = 0V) of the NJM2387 ?
What is the Quiescent current (the CONTROL terminal voltage (Vcont) = 0V) of the NJM2387 ?
The Quiescent current (Vcont=0V) vs. Input voltage characteristics of NJM2387_10V (typ. sample) is shown in Figure 1.

The internal circuit configuration of the NJM2387 ON/OFF control block is different from other products. In this product, When an input voltage is applied and Vcont becomes low, current flows from the Vin terminal through the internal circuit and out of the CONT terminal. Therefore, the Quiescent current (Vcont = 0V) is large.
If you would like a product that has the same performance as NJM2387 but has a small Quiescent current(OFF), please consider "NJM2387A".
