The capacitor’s equivalent series resistance must limit the Drive Output current to 1.0 A. An additional series resistor
may be required when using tantalum or other low ESR capacitors. The positive output can provide excellent line and
load regulation by connecting the R2/R1 resistor divider as shown.
