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 0 VIN 5.5 V
VBIAS(1) BIAS supply voltage VOUT + VDO (VBIAS)(2) VOUT + 1.4 (2) 5.5 V
VOUT Output voltage 0.8 3.3 V
IOUT Output current 0 500 mA
COUT Output capacitor 2.2 µF
CIN Input capacitor(3) 1 µF
CBIAS Bias capacitor 0.1 1 µF
TJ Operating junction temperature –40 125
BIAS supply is required when VIN is below VOUT + 1.62 V.
VBIAS has a minimum voltage of 2.7 V or VOUT + VDO (VBIAS), whichever is higher.
If VIN and VBIAS are connected to the same supply, the recommended minimum capacitor for the supply is 4.7 μF.
