UA78M33CDCYR TI Voltage Regulators - Linear
The UA78M33C is a 500mA positive voltage regulator providing fixed 3.3V output. It operates from 5.3V to 25V input and features internal current limiting, thermal shutdown, and safe-area compensation. The device provides 5% output tolerance and requires minimal external components. The DCY package is SOT-223 for surface mounting. Selection is standard for local 3.3V regulation in medium-current applications. Applications include consumer electronics, industrial power supplies, microcontroller power supplies, and as a post-regulator for switching converters requiring cost-effective linear regulation from 5V or higher input rails.
