LW5218 - 500mA High PSRR LDO

Download the LW5218 datasheet PDF. This datasheet also covers the LW5208 variant, as both devices belong to the same 500ma high psrr ldo family and are provided as variant models within a single manufacturer datasheet.

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.

Key Features

  • Output Accuracy: ±1.5%.
  • Low Quiescent Current: 40uA.
  • Low Dropout Voltage: 42mV@100mA/3.3V.
  • High PSRR: 95dB@1KHz, 1mA.
  • Output Current: 500mA.
  • Excellent Line and Load Transient Response.
  • Operating Voltage Range: from 1.5V to 6.0V.
  • Output Voltage Range: from 0.8V to 5.0V.
  • Over-Temperature Protection.
  • Current Limiting Protection.
  • Output Short-Circuit Protection.
  • Available in SOT23, SOT23-3L, SOT23-5L and DFN1x1-4L Packages.
