UA78L05CPK TI Voltage Regulators - Linear
The UA78L05 is a 100mA fixed output positive voltage regulator providing 5V output, operating from 7V to 20V input. It features internal current limiting and thermal shutdown. The device requires no external components for basic operation, though bypass capacitors may improve transient response. Output voltage tolerance is 5% over temperature. The UA78L05 is packaged in SOT-89-3 for surface-mount designs. Selection is standard for local 5V regulation in low-current applications requiring surface-mount packaging. Applications include consumer electronics, small instrumentation, microcontroller power supplies, voltage references for op-amp circuits, and as a post-regulator for switching converters requiring cost-effective linear regulation.
