6.3.7 Minimum Load

The TPS735 device is stable with no output load. To meet the specified accuracy, a minimum load of 500 μA is required. If the output is below 500 µA and if the junction temperature is approximately 125°C, the output can increase enough to turn on the output pulldown. The output pulldown limits voltage drift to 5% (typically) but ground current can increase by approximately 50 μA. In most applications, the junction does not reach high temperatures at light loads because little power is dissipated. As a result, the specified ground current is valid at no load in most applications.
