Output voltage Typical max current output1 Input voltage range2
1.8 V 500 mA 3 V – 36 V

1 Typical continuous output current at 24 V in. Actual achievable continuous output current is a function of input voltage and is limited by thermal dissipation. See the output current graphs on the product pages for more information.
2 Minimum input voltage is subject to dropout voltage considerations; see the dropout voltage section of product pages for more information.
