L78M12ABDT-TR Description

Short technical summary and product information.

The STMicroelectronics L78M12ABDT-TR is a precision 500 mA positive voltage regulator designed for a wide range of applications. It features a fixed output voltage of 12V and an output current capability of up to 0.5 A. The device includes built-in thermal overload protection, short circuit protection, and output transition SOA protection, making it highly reliable.

 

This regulator is available in a DPAK surface mount package (TO-252-3, DPak (2 Leads + Tab), SC-63). It operates over an extended temperature range from -40°C to 125°C. The input voltage can be as high as 35V, with a typical quiescent current of 6 mA and a PSRR of 55dB at 120Hz.

 

Designed for local on-card regulation, the L78M12ABDT-TR helps eliminate distribution problems associated with single-point regulation. While primarily a fixed voltage regulator, it can be used with external components to achieve adjustable voltage and current outputs if needed. Its robust design ensures it is essentially indestructible with adequate heat sinking.
