Product Overview
The L78L06ABZ from STMicroelectronics is a three-terminal positive voltage regulator from the L78L series, providing a fixed 6V output at up to 100 mA in a through-hole TO-92 package. It features internal current limiting, thermal shutdown, and short-circuit protection, requiring no external components for operation. The A-grade version offers +/-4% output voltage tolerance over the -40°C to +125°C temperature range.
