Output voltage range Typical max current output1 Input voltage range2 Low-voltage cutoff
4.2 V – 15 V 3 A 4.2 V – 45 V none

1 Typical continuous output current at 30 V in and 9 V out. Actual achievable continuous output current is a function of input and output voltages and is limited by thermal dissipation. See the output current graph on the product page for more information.
2 Input voltage must be higher than the output voltage and is subject to dropout voltage considerations; see the dropout voltage section of product pages for more information.
