Overview

The AP2210K-3.3TRG1 is a 300mA fixed output linear voltage regulator designed for low-dropout applications requiring high stability and low noise. It features a high PSRR of 75dB at 100Hz and includes a dedicated enable pin for logic-controlled power management. The device is housed in a compact SOT-23-5 package, making it suitable for space-constrained power distribution tasks.

Why Choose This Part

This regulator offers robust protection features including over-current, thermal shutdown, and reverse polarity protection. It maintains excellent ESR stability and provides high accuracy with a 1 percent tolerance, ensuring reliable performance across a temperature range of -40 to 125 degrees Celsius.
