6.5 Electrical Characteristics: 3.3-V Versions
Limits are assured by production testing or correlation techniques using standard Statistical Quality Control (SQC) methods.
Unless otherwise specified: MIN (minimum) and MAX (maximum) specifications in apply over the full Operating Temperature
Range and TYP (typical) values apply at T_J = 25°C, V_IN = V_OUT(NOM) + 1 V, I_OUT = 1 mA, C_OUT = 2.2 μF for 5-V parts and 4.7
μF for 3.3-V parts. FEEDBACK pin is tied to VTAP pin, OUT pin is tied to SENSE pin.
