Overview
The TPS71713DCKR is a low-dropout (LDO) linear regulator from Texas Instruments, part of the TPS717 family. This device is designed to offer high performance with ultra-low current consumption, making it ideal for battery-powered and small form factor portable equipment. The TPS71713DCKR features a fixed output voltage of 1.3V and can supply up to 150mA of current. It is available in a small 5-pin SC-70 package, which is suitable for applications where space is limited.
