Electrical Characteristics: All Voltage Options (continued)
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 TJ = 25°C, VIN = VOUT(NOM) + 1 V, IOUT = 1 mA, COUT = 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.
