LM78L12ACZ Description

Short technical summary and product information.

The LM78L12ACZ is a 12V positive linear voltage regulator designed for a wide range of applications. It operates with an input voltage up to 30V and provides a stable 12V output at up to 100mA. This regulator includes built-in thermal overload protection and output current limiting, enhancing its reliability.

 

Designed as a replacement for Zener-diode and resistor combinations, the LM78L series offers improved output impedance and lower quiescent current. It can provide local, on-card regulation, which helps eliminate distribution problems associated with single-point regulation. The device is suitable for use in logic systems, instrumentation, and industrial power delivery.

 

The LM78L12ACZ is supplied in a TO-92 package and is rated for an operating temperature range of -40°C to 125°C. No external components are required for stability, simplifying circuit design and implementation.
