5.3 Recommended Operating Conditions

over operating junction temperature range (unless otherwise noted)
MIN NOM MAX UNIT
VIN Input supply voltage range 3.0 40 V
VOUT Output voltage range (Fixed only)(1) 1.2 12 V
VOUT Output voltage range (Adjustable only)(1) 1.2 38 V
VEN Enable voltage range 0 40 V
IOUT Output current 0 300 mA
CIN Input capacitor(2) 0.47 µF
COUT Output capacitor (3) 4.7 100 µF
CFB ADJ to GND capacitor(3) 15 pF
CFF Feed-forward capacitor (4) 10 nF
TJ Operating junction temperature –40 125 °C
(1) This output voltage range does not include device accuracy or accuracy of the feedback resistors.
(2) An input capacitor is not required for LDO stability. However, an input capacitance with an effective value of 0.1μF minimum is recommended to counteract the effect of source resistance and inductance, which can in some cases cause symptoms of system level instability such as ringing or oscillation, especially in the presence of load transients.
(3) The upper limit for the capacitor on the ADJ pin with respect to GND impacts the stable operation of the voltage regulator in adjustable configuration. For CFB capacitor higher than limits mentioned in Recommended Operating Conditions table, use CFF capacitor.
(4) The CFF capacitor improves transient, noise, and PSRR performance, but is not required for regulator stability. Using a higher capacitance CFF is permissible but start-up time increases.
