5.3 Recommended Operating Conditions

over operating free-air temperature range (unless otherwise noted)
MIN NOM MAX UNIT
VIN  Input supply voltage VOUT + VDO (VIN) VOUT + 0.3 5.5 V
VEN  Enable supply voltage VIN 5.5 V
VBIAS(1)  BIAS supply voltage VOUT + VDO (VBIAS)(2) VOUT + 1.6(2) 5.5 V
VOUT Output voltage 0.8 3.6 V
IOUT Output current 0 1.5 A
COUT Output capacitor (legacy chip) 0 µF
Output capacitor (new chip) 2.2 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 + VDO (VBIAS).
(2) VBIAS has a minimum voltage of 2.7 V or VOUT + VDO (VBIAS), whichever is higher (new chip).
(3) If VIN and VBIAS are connected to the same supply, the recommended minimum capacitor for the supply is 4.7 μF.
