SUPER-SMALL PACKAGE CMOS VOLTAGE REGULATOR
S-817 Series
Seiko Instruments Inc.
17
The S-817 Series can be configured as a constant current circuit. Refer to
Figure 15 and 16
.
Constant amperage (I
O
) is calculated using the following equation (V
OUT(E)
: Effective output voltage):
I
O
=
(V
OUT(E)
÷
R
L
)
+
I
SS
.
Please note that it is impossible to set constant amperage I
O
in case of circuit (1) of
Figure 15
to the
value exceeding the drive ability of the S-817.
However, circuit (2) of
Figure 16
is an example to set constant amperage to the value exceeding the
drive ability of the S-817. Circuit (2) incorporates a current boosting circuit. The maximum input voltage
of the constant current circuit is the value obtained by adding 10 V to voltage of the device (V
O
). It is not
recommended to attach a capacitor between the S-817 power source VIN and VSS pin or between
output VOUT and VSS pin because rush current flows at powering on. An example of input voltage
