ELECTRICAL CHARACTERISTICS Unless otherwise stated, these specifications apply for TA = 0°C to 70°C.
TRMPWR = 3.3V, DISCNCT = 3.3V, RDISCNCT = 0 ohms. TA = TJ.
Note 1: Measuring each termination line while other 17 are low (0.2V).
Note 2: Guaranteed by design. Not 100% tested in production.
Note 3: Output Capacitance is measured at 0.5V.
Note 4: Tested by measuring IOUT with VOUT = 0.2V and VOUT = VREG - 0.1V then calculating the impedance.
