L78L05ABZ Description

Short technical summary and product information.

The L78L05ABZ is a linear voltage regulator from STMicroelectronics that provides a fixed 5V output and is rated for 100mA output current. It is housed in a TO-92-3 through-hole package, making it suitable for compact circuit board layouts.

 

As a fixed-output linear regulator, it delivers a stable 5V supply for low-power circuits. The TO-92-3 package is a widely used through-hole package for low-power devices, allowing straightforward insertion into standard PCBs.

 

Linear regulators dissipate excess voltage as heat, so thermal design should account for the difference between input and output voltage and the load current. The L78L05ABZ is appropriate for applications requiring a simple, low-cost 5V rail with low output current.

 

The device belongs to the L78L series of linear regulators and is classified under Power Management (PMIC) in the integrated circuits category. Its fixed output voltage simplifies circuit design without requiring external resistor networks for adjustment.
