Description

The REG103GA-A from Texas Instruments is a high-quality, high-performance voltage regulator designed to offer a combination of small size, low dropout voltage, and high output current.

  • Output Current: 500mA
  • Dropout Voltage: 500mV at full load
  • Shutdown Function: Reduces the supply current to less than 0.01µA
  • Error Flag: Warns of a low output voltage
  • Line and Load Transient Response: Excellent
  • Input Voltage Range: 2.7V to 10V
  • Output Voltage: Fixed output voltage of 3.3V, adjustable version available between 1.5V and 10V
  • Package: Small, surface-mount SOT223 package
  • Temperature Range: -40°C to +125°C
