Electrical Characteristics (continued)
over operating junction temperature range (TJ = â40°C to +125°C), VIN = 1.4 V or VIN = VOUT(nom) + 0.3 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 = 22 μF, CNR/SS
= 0 nF, CFF = 0 nF, and PG pin pulled up to VIN with 100 kΩ (unless otherwise noted); ypical values are at TJ = 25°C
