Ultra-Low Noise, High PSRR LDO, 250 mA Linear Regulator for RF and Analog Circuits
  • SKU
    WL2863E
  • Category
    Power Management - LDO
  • Application
    Mobile Devices, IoT / Emerging

The WL2863E is a linear regulator capable of supplying 250-mA output current. Designed to meet the requirements of RF and analog circuits, the WL2863E device provides low noise, high PSRR, low quiescent current and very good load /line transients.

The device is designed to work with a 1 μF input and 1 μF output ceramic capacitor (no separate noise Operation bypass capacitor is required).

The WL2863E regulators are available in standard SOT-23-5L Package. Standard products are Pb-free and Halogen-free.

Applications
– Cell phones, radiophone, digital cameras
– Bluetooth, wireless handsets
– HiFi products
– Other portable electronic devices
