LW5208 - 500mA High PSRR LDO

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.

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.
