LP38798 - 800-mA Ultra-Low-Noise High-PSRR LDO

General Description

The LP38798-ADJ is a high-performance, low-noise LDO that can supply up to 800 mA output current.

Key Features

  • 1 Wide Operating Input Voltage Range: 3 V to 20 V.
  • Ultra-Low Output Noise: 5 µVRMS (10 Hz to 100 kHz).
  • High PSRR: 90 dB at 10 kHz, 60 dB at 100 kHz.
  • ±1% Output Voltage Initial Accuracy (TJ = 25°C).
  • Very Low Dropout: 200 mV (Typical) at 800 mA.
  • Stable with Ceramic or Tantalum Output Capacitors.
  • Excellent Line and Load Transient Response.
  • Current Limit and Overtemperature Protection.
  • Create a Custom Design Using the L.
