LDO VOLTAGE REGULATOR

The WLP-4B is a small wafer level package measuring 1.16 x 0.79 x 0.58 mm, effecting high-density mounting. The S-L2985 is designed for use with small capacitance (0.47 µF) ceramic capacitors. The high ripple rejection ratio of 80 dB typical assures compatibility with noise sensitive environments while the low current consumption and ON/OFF circuit greatly increase batter life and overall energy efficiency.
