78L05 Description

Short technical summary and product information.

The 78L05 is a positive voltage regulator IC from NEC, part of the L78Lxx series. It is designed to provide a stable 5V output voltage, making it suitable for a wide range of electronic projects. The '78' indicates a positive voltage regulator, '05' specifies the 5V output, and 'L' denotes its low current capability of up to 100mA.

This voltage regulator incorporates fundamental protection features such as thermal shutdown and internal current limiting, making it robust against overloads. While it can deliver up to 100mA, it is noted that this component can generate significant heat, and the use of a heat sink is recommended for applications drawing more current. The 78L05 can also be used in conjunction with power pass elements to construct higher current voltage regulators.

Compared to its higher current counterpart, the 7805, the 78L05 is smaller and designed for lower power applications. Its fixed output voltage and built-in protection make it a reliable choice for power supply circuits where a stable 5V is required.
