L7981ATR - Brand New STMicroelectronics DC Switching Regulators
-
Description
The L7981ATR is a three-terminal negative regulator available in TO-220, TO-220FP, and D²PAK packages. It is part of the L79 series and offers several fixed output voltages, making it suitable for various applications. This regulator provides on-card regulation, eliminating distribution issues associated with single-point regulation. It is particularly well-suited for split power supplies and can deliver an output current of over 1.5 A with adequate heat sinking. While primarily designed as a fixed voltage regulator, it can be used with external components to achieve adjustable voltages and currents.
