at TJ = –40°C to +125°C, VINP(nom) = VOUTP(nom) + 1 V or VIN(nom) = 3.3 V (whichever is greater), VINN(nom) = VOUTN(nom) – 1 V or
VINN(nom) = –3.3 V (whichever is less), VEN = VINP, IOUT = 1 mA, CINx = 2.2 μF, COUTx = 10 μF, CFFx = CNR/SS = open, R1N = R2N
10 kΩ, and FBP tied to OUTP (unless otherwise noted); typical values are at TJ = 25°C

(1) To ensure VOUT does not drift up while the device is disabled, a minimum load current of 5 µA is required.
(2) VOUT(target) = 0 V, R1N = 10 kΩ, R2N = open.
(3) The device is not tested under conditions where the power dissipated across the device, PD, exceeds 2 W.
