Product Overview

The REG103UA-3.3 is a 3.3V fixed output low-noise low-dropout (LDO) Linear Regulator with low ground pin current. Its new DMOS topology provides significant improvement over previous designs, including low-dropout (LDO) voltage and better transient performance. In addition, no output capacitor is required for stability, unlike conventional low-dropout (LDO) regulators that are difficult to compensate and require expensive low ESR capacitors greater than 1µF. Typical ground pin current is only 1mA (at IOUT = 500mA) and drops to 0.5µA in not enabled mode. Unlike regulators with PNP pass devices, quiescent current remains relatively constant over load variations and under dropout conditions. Accuracy is maintained over temperature, line and load variations. Key parameters are tested over the specified temperature range.
  • Output capacitor not required for stability
  • Fast transient response
  • 33µVrms Very low noise
  • ±2% High accuracy
  • Fold-back current limiting
  • Thermal protection
  • Green product and no Sb/Br

Applications

Portable Devices, Consumer Electronics, Communications & Networking, Power Management
