Circuit
- Isolation Voltage DC500V
- Low Drift 50mV/8H
- Temp. Coefficient ±0.02%/°C
- Operating Temp. Range
-20°C to +70°C - Recommended Capacitor
(Temp. derating required)   C1=100µF
- RoHS Compliance   C2,C3=1µF
Basically, external capacitors are not required,
but noise can be lowered by reducing power
line impedance and load line impedance.
