DIOAP2112K-3.3TRG1
Overview
The AP2112K-3.3TRG1 is a 600mA CMOS low dropout linear regulator (LDO) designed to provide a stable 3.3V output from input voltages up to 6V. It features low quiescent current and high output accuracy, making it suitable for battery-powered applications where efficiency and space are critical. The device includes built-in protection mechanisms such as thermal shutdown and foldback current limiting.
Why Choose This Part
This regulator is designed for stability with a small 1.0uF ceramic output capacitor, reducing overall PCB footprint and cost. It offers a high PSRR of 65dB at 1kHz for noise-sensitive circuits and includes an auto-discharge function to ensure power rails are safely pulled low when the device is disabled.
Applications
Key Specifications
Getting Started
When designing with the AP2112K, place a 1.0uF ceramic capacitor close to the VIN and VOUT pins for stability. Utilize the active-high Enable (EN) pin to manage power sequencing; if control is not needed, tie this pin directly to VIN. Ensure the thermal pad or ground pins have sufficient copper pour to manage heat dissipation during 600mA peak loads.
