The LDK130M18R molecule is a breakout module for the STMicroelectronics LDK130M18R low‑dropout (LDO) linear regulator, fixed at 1.8 V output with a 300 mA maximum load, capable of accepting input voltages from 1.9 V up to 5.5 V. It features ultra‑low quiescent current (~30–60 µA), very low dropout (~100–200 mV at 100 mA load), ±2 % output accuracy, an enable/shutdown pin, and built‑in over‑current and thermal protection. The molecule includes all necessary support circuitry—input and output bypass capacitors, the enable pull‑up/down network—and breaks out VIN, VOUT, EN, and GND.
