LM140K-15 +BOM

LM140K-15 is a 1A voltage regulator

LM140K-15 General Description

Designed with a focus on high-performance voltage regulation, the LM140K-15 from Texas Instruments is a standout product in the LM140 series. The fixed 15-volt output voltage makes it a reliable choice for applications requiring a constant voltage supply. The TO-3 metal can package ensures robustness and efficient heat dissipation, suitable for industrial and commercial use. With a maximum output current of 1.5 amperes, this regulator is capable of powering medium to moderately high current loads with ease. Its low dropout voltage and excellent line and load regulation characteristics contribute to stable voltage output across diverse operating conditions
