6 / 24 page © 2006 Fairchild Semiconductor Corporation www.fairchildsemi.com FAN5099 Rev. 1.1.5 6 Electrical Characteristics (Continued) Notes: 2. All limits at operating temperature extremes are guaranteed by design, characterization, and statistical quality control. 3. AC specifications guaranteed by design/characterization (not production tested). 4. 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. 5. Test Conditions: VLDO_IN = 1.5V and VLDO_OUT = 1.2V. Unless otherwise noted, VCC = 5V, TA = 25°C, using the circuit in Figure 1. The ‘•’ denotes that the specifications apply to the full ambient operating temperature range.(2, 3) Symbol Parameter Conditions Min. Typ. Max.
