MC79L05ABP Description

Short technical summary and product information.

The MC79L05ABP from ON Semiconductor is a low-cost, 100 mA negative voltage regulator designed for numerous applications requiring a regulated negative voltage. This device features internal thermal overload protection and current limiting, making it robust for various operating conditions. It requires no external components for most applications, simplifying circuit design.

 

Key electrical specifications include a fixed -5V output voltage and a maximum output current of 100mA. The typical voltage dropout is 1.7V at 40mA. The regulator operates within a temperature range of -40°C to 125°C.

 

Packaged in a TO-92 (TO-226) package, the MC79L05ABP is suitable for through-hole mounting. Its design offers substantial advantages over traditional resistor/Zener diode configurations, providing a stable and reliable negative voltage supply for on-card regulation or other moderate current needs.
