Description

Note 1: At 30 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. Note 2: Minimum input voltage is subject to dropout voltage considerations; see the dropout voltage section of product pages for more information.
