Electrical Characteristics (continued)
Over operating junction temperature range (TJ = â40°C to +125°C), VIN = 1.4 V or VIN = VOUT(nom) + 0.4 V (whichever is
greater), VBIAS = open, VOUT(nom) = 0.8 V(1), OUT connected to 50 Ω to GND(2), VEN = 1.1 V, CIN = 10 μF, COUT = 47 μF, CNR/SS
without CFF, and PG pin pulled up to VIN with 100 kΩ, unless otherwise noted. Typical values are at TJ = 25°C.
