Description
I/O
5
Out:
O
Open-collector type (darlington) output terminal.
The absolute maximum rating of output current is
100 mA
Use with a steady-state output current under 50
mA.
6VCC:
The terminal for applying supply voltage.
Use with a operating supply voltage within the
range of 3.6 V to 34 V.
7VREF:O
The output terminal for the reference voltage (2.46
V)
Use with a load current
−3 mA or under.
This terminal is incorporating the short-circuit
protection circuit, and the short-circuit current is
about
−20 mA. Use the V
REF for the reference
input setting of the error amplifier.
8IN
+:I
The noninverted input terminal of the error ampli-
fier.
For common-mode input, use in the range of
− 0.1
V to
+0.8 V.
9IN
−:I
The inverted input terminal of the error amplifier.
For common-mode input, use in the range of
− 0.1
V to
+0.8 V.
10
FB:
O
The output terminal of the error amplifier.
The source current is about
−120 µA, and the sink
current is about 8 mA.
Correct the frequency characteristics of the gain
and the phase by connecting a resistor and a ca-
pacitor between this terminal and IN
− terminal.
