Timothy I. ★★★★★ Oct 22, 2026

The standby current being only 2mA is perfect for the sensor node I built, it sips power. The thermal shutdown gives me peace of mind, and it regulates at a clean 5V without any hassle.

Matthew ★★★★★ Oct 21, 2026

Used this on a battery-powered project and the dropout voltage is low enough that I'm getting a clean 5V even as the cells drain. It handles current draw without any noticeable heat buildup in normal use.

Emma Y. ★★★★★ Oct 20, 2026

The 2mA standby current is a lifesaver for my battery-powered projects—it sips power instead of draining it. The SOT-223 package takes a bit of patience with a soldering iron, but once it's down, it holds steady at a clean 5V. Thermal shutdown gives me peace of mind when I push it close to 1A.
