LW52XX Series 500m A High PSRR LDO With Fast-Start GENERAL DESCRIPTION The LW52XX Series is a group of voltage regulators with high accuracy, high speed, low drop-out, high ripple rejection and fast discharge function. The current limiter’s fold-back circuit operates as a short circuit protection as well as the output current limiter for the output pin. Output voltage is selectable from 0.8V to 5.0V which fixed by laser trimming technologies, Step=100m V. The LW52XX Series is available in SOT23, SOT233L, SOT23-5L and DFN1x1-4L packages.
