5.3 Recommended Operating Conditions

over operating free-air temperature range (unless otherwise noted)
MIN TYP MAX UNIT
VIN Input voltage 3 40 V
VOUT Output voltage 1.2 18 V
IOUT Output current 0 150 mA
FEN Enable pin frequency(1) 5 kHz
VEN High voltage (I/O) 0 40 V
COUT Output capacitor(3) 2.2 220 µF
ESR Output capacitor ESR requirements(4) 0.001 2 Ω
CIN Input capacitor(2) 0.1 1 µF
TJ Operating junction temperature –40 150 °C
(1) Minimum pulse time on the EN pin is 100 µs.
(2) For robust EMI performance the minimum input capacitance is 500 nF.
(3) Effective output capacitance of 1 µF minimum required for stability.
(4) If using a large ESR capacitor it is recommended to decouple this with a 100-nF ceramic capacitor to improve transient performance.
