APPLICATIONS INFORMATION

GROUND CURRENT

The major source for ground current in the ADP198 is an internal

4 MΩ pull-down resistor on the enable pin. Figure 23 shows

the typical ground current when VEN = VIN and varies from

1.65 V to 6.5 V.

Figure 23. Ground Current vs. Load Current

As shown in Figure 24, an increase in quiescent current can occur

when VEN ≠ VIN. This is caused by the CMOS logic nature of the

level shift circuitry as it translates a VEN signal ≥1.2 V to a logic

high. This increase is a function of the VIN − VEN delta.
