The D type provides separate internal circuit power supply (VDD pin) and output voltage setting pin (VOUT pin) in the
IC, making it ideal for the following applications.

is impedance between the VOUT pin and VSS pin in the IC chip. The internal resistance
between the VOUT pin and VSS pin is as follows :
(1) S-835xx18 : 2.1 MΩ to 14.8 MΩ
(2) S-835xx20 : 1.4 MΩ to 14.8 MΩ
