Overview
The UA78L10ACPK is a fixed-voltage linear regulator from Texas Instruments, part of the UA78L series. This regulator is designed to provide stable voltage regulation across a wide range of applications. It is particularly useful for on-card regulation, helping to eliminate noise and distribution problems associated with single-point regulation. The UA78L10ACPK can also be used in conjunction with power-pass elements to create high-current voltage regulators.
