The Vs26 regulator cannot completely replace the tlv1117-33 because they have some different characteristics and parameters. The TLV1117-33 is a low-voltage differential linear regulator with high stability and accuracy for applications requiring low noise, low drift and high stability. The VS26 regulator is more suitable for some applications with low cost, low power consumption and general performance requirements. Therefore, when choosing a regulator, it is necessary to select the most suitable device according to the specific application requirements.
