Manufacturer: Texas Instruments

Overview: Product Folder Sample & Buy Technical Documents Tools & Software Support & Community LP8900 SNVS542E – MAY 2008 – REVISED JUNE 2016 LP8900 200-mA Ultra-Low-Noise Dual LDO For RF and Analog Circuits.

General Description

The LP8900 is a dual LDO capable of supplying 200mA output current per regulator.

Designed to meet the requirements of RF and analog circuits, the LP8900 provides low device noise, high PSRR, low quiescent current, and superior line transient response figures.

Using new innovative design techniques, the LP8900 offers class-leading device noise performance without a noise bypass capacitor.

Key Features

  • 1 Input Voltage Operation: 1.8 V to 5.5 V.
  • Output Voltage: 1.2 V to 3.6 V.
  • Accuracy Over Temperature: 1%.
  • Output Voltage Noise: 6 µVRMS.
  • PSRR: 75 dB at 1 kHz.
  • Dropout: 110 mV at 200 mA Load.
  • Quiescent Current: 48 µA per Regulator.
  • Start-Up Time: 80 µs.
  • Stable With Ceramic Capacitors as Small as 0402.
  • Thermal-Overload and Short-Circuit Protection 2.
