Additional details would normally include specific voltage and current ratings, package type, and operating temperature range. However, due to its end-of-life status, these specifics are difficult to confirm. When using any component, always refer to the manufacturer's datasheet for complete and accurate specifications prior to design and implementation. This particular part is likely an older component; therefore, newer, more efficient regulators may be available.
