Positive fixed output LDO regulator, offering a stable 4.2V output with a maximum current of 0.21A. Features a compact 4-pin HSON surface-mount package (1.4mm x 1.2mm x 0.55mm) with a 0.5mm pin pitch. Operates from 1.8V to 6V input, with a typical dropout voltage of 0.165V at 200mA and ±1% accuracy. Includes current limit, on-off control, and thermal protection for enhanced reliability across a -40°C to 85°C temperature range.
