Electrical Characteristics (Continued)
Unless otherwise noted, VCC = 5V, TA = 25°C, using circuit in Figure 1.
The ‘•’ denotes that the specifications apply to the full ambient operating temperature range. See Notes 4 and 5.

Notes:
4. All limits at operating temperature extremes are guaranteed by design, characterization, and statistical quality
control.
5. AC specifications guaranteed by design/characterization (not production tested).
6. For a case when VCC is higher than the typical 5V VCC; voltage observed at VCC pin when the internal shunt
regulator is sinking current to keep voltage on VCC pin constant.
7. Test Conditions: VLDO_IN = 1.5V and VLDO_OUT = 1.2V
