6.3 Recommended Operating Conditions

over operating free-air temperature range (unless otherwise noted)
MIN NOM MAX UNIT
VIN Input supply voltage 0.65 VBIAS – 0.1 V
VBIAS(1)       BIAS supply voltage 1.7 6 V
VEN Enable voltage 6 V
VOUT  Output voltage 0.65 3.6 V
IOUT   Output current 0 1.5 A
COUT    Output capacitor 10 µF
CIN Input capacitor(3) 1 µF
CBIAS  Bias capacitor 0.1 1 µF
TJ  Operating junction temperature –40 125 ℃
(1) BIAS supply is required when VIN is below VOUT + 1.62 V.
(2) If VIN and VBIAS are connected to the same supply, the recommended minimum capacitor for the supply is 4.7 μF.
