The LM2940SX-5.0/NOPB from Texas Instruments is a 1-A positive voltage regulator designed for high performance and reliability. It features a low dropout voltage, typically 0.5 V at 1 A, with a maximum of 1 V across the entire operating temperature range of -40°C to 125°C.
This regulator supports an input voltage range from 6 V to 26 V and includes features such as reverse battery protection, internal short circuit current limit, and mirror image insertion protection. A quiescent current reduction circuit minimizes ground current when the input-output differential exceeds approximately 3 V, resulting in only 30 mA of quiescent current at 1 A output with a 5 V differential.
The LM2940SX-5.0/NOPB is supplied in a TO-263-3 surface-mount package, making it suitable for various electronic designs. It is designed for applications requiring stable voltage regulation with minimal power loss due to its low dropout characteristic.
