AP2112K-3.3TRG1 Datasheet Explained: Pinout, Specs, and 3.3V LDO Design for ESP32/ESP8266

Every ESP32 or ESP8266 board needs a stable 3.3 V rail, and the chosen regulator affects battery life and board size. The AP2112K-3.3TRG1 from Diodes Incorporated is a frequent choice for the job, pairing a compact SOT-25 package with ±1.5% output accuracy, 600 mA of guaranteed output current, and a typical quiescent current of 55 […]
USBLC6-2SC6 Datasheet Explained: Pinout and ESD Protection

Universal Serial Bus (USB) ports take a hit from electrostatic discharge (ESD) whenever a charged person, cable, or peripheral touches the interface. Because the connectors provide ESD with a direct path into the printed circuit board (PCB), protection should be placed close to the connector, where it diverts transients before they reach the USB transceiver. […]
