Note 1: Instantaneous limitation of the switch. Actual achievable maximum continuous current is a function of input and output voltage and is limited by thermal dissipation. See the output current graphs on the product pages for more information.
Note 2: The U5Z6F12 is intended as a 12 V regulator with a max continuous output current of 100 mA, but it also has a 5 V output that can deliver up to 300 mA continuous when the 12 V output current is zero (using the 5 V output reduces the current available on the 12 V output).
Note 3: The U5Z6F12 maximum input voltage is 5.5 V (i.e. it is intended to run from a 5V supply).

This step-up voltage regulator consists of an isolated DC-to-DC power module in front of a step-up (boost) regulator. This enables up to 100 mA continuous at 12 V out from a 5 V input with full galvanic isolation between the input and output. The 5 V, 300 mA output of the isolation IC is also available.
