Product Overview

The REG103UA-A is a low-noise low-dropout Linear Regulator with low ground pin current. Its new DMOS topology provides significant improvement over previous designs, including low-dropout voltage and better transient performance. In addition, no output capacitor is required for stability, unlike conventional low-dropout regulator that is difficult to compensate and require expensive low ESR capacitors greater than 1µF. Typical ground pin current is only 1mA and drops to 0.5µA in not enabled mode. Unlike regulator with PNP pass devices, quiescent current remains relatively constant over load variations and under dropout conditions. The device has very low output noise, making it ideal for use in portable communications equipment. On-chip trimming results in high output voltage accuracy. Accuracy is maintained over temperature, line and load variations. The device is well protected - internal circuitry provides a current limit that protects the load from damage.
  • Output capacitor NOT required for stability
  • Fast transient response
  • Fold-back current limit
  • Thermal protection
  • 33µVrms Very low noise
  • ±2% Maximum high accuracy
  • High efficiency - IGND = 1mA at IOUT = 500mA, not enabled - IGND = 0.5nA
  • Green product and no Sb/Br

Applications

Portable Devices, Communications & Networking, Sensing & Instrumentation, Power Management
