I’ll turn this into a cited application and usage guide for the AP2112K-3.3TRG1, verify the datasheet details and alternatives, then save the finished guide in the project.
The AP2112K-3.3TRG1 is a fixed 3.3 V CMOS low-dropout linear regulator with an enable input, active output discharge, and a guaranteed minimum continuous output current of 600 mA. It is commonly used to generate a clean 3.3 V rail for microcontrollers, sensors, and RF circuitry from a 3.6 V to 6 V source.
1. Quick Specifications
Important: Absolute maximum ratings are stress limits, not design targets. Normal operation should remain within the recommended input and temperature ranges and below the thermally allowable load current.
2. Pinout & Connections
The SOT25 pin assignment is VIN-1, GND-2, EN-3, NC-4, and VOUT-5.
Created the cited AP2112K-3.3TRG1 Application and Usage Guide. It covers specifications, pin connections, application wiring, thermal/layout guidance, verified alternatives, sourcing, and identified verification limits.
