9.1.1 DCR01 Single Voltage Output

The DCR01 can be used to provide a single voltage output by connecting it as shown in Figure 9-1. The ERROR output signal is pulled up to the value of VOUT. The value of RERR depends on the loading on the ERROR line, however, the total load on the ERROR line must not exceed the value given in the Electrical Charcteristics.

The output can be permanently enabled by connecting the ENABLE pin to the VREC pin. The DCR01 can be enabled remotely by connecting the ENABLE pin to VREC through a pullup resistor (REN); the value of this resistor is not critical for the DCR01 as only a small current flows. The switch SW1 can be used to pull the ENABLE pin LOW, thus disabling the output. The switching devices can be a bipolar transistor, FET, or a mechanical device; the main load that it sees is REN.
