7.3.7 Minimum Load

The TPS735-Q1 family of devices is stable and well-behaved with no output load. To meet the specified accuracy, a minimum load of 500 μA is required. Below 500 μA and at junction temperatures near 125°C, the output can drift up enough to cause the output pulldown to turn on. 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 very little power is dissipated. Therefore, the specified ground current is valid at no load in most applications.
