Electrical Characteristics (continued)

over operating junction temperature range (TJ = –40°C to +125°C), VIN = 1.4 V or VIN = VOUT(nom) + 0.5 V (whichever is

greater), VBIAS = open, VOUT(nom) = 0.8 V

(1), OUT connected to 50 Ω to GND, V

EN = 1.1 V, CIN = 10 µF, COUT = 47 µF, CNR/SS =

0 nF, CFF = 0 nF, and PG pin pulled up to VIN with 100 kΩ (unless otherwise noted); typical values are at TJ = 25°C
