LT3078 - 5.5V 5A Ultra-Low Noise High PSRR 55mV Dropout Ultra-Fast Linear Regulator

General Description

The LT®3078 is a low voltage, ultra-low noise, high power-supply rejection ratio (PSRR), and ultra-fast transient response linear regulator.

The device supplies up to 5A with a typical dropout voltage of 55mV.

Key Features

  • Ultra-low RMS Noise: 1.3μVRMS (10Hz to 100kHz).
  • Ultra-low Spot Noise: 3.5nV/√Hz at 10kHz.
  • Ultra-low1/fNoise:11µVP-P from0.1Hz to 10Hz.
  • High PSRR at High-Frequency: 49dB at 1MHz.
  • Ultra-fast Transient Response.
  • Dropout Voltage: 55mV Typical.
  • Digitally Programmable VOUT: 0.5V to 4.2V.
  • High Accuracy: ±1.5% Over Line, Load, and Temperature.
  • Precise Current Monitor: ±3% accuracy at 5A.
  • Programmable Current Limit: ±3% at 5A.
  • Input Voltage Range: 0.
