Description

  • Pololu 3.3V Step-up Voltage Regulator U1V11F3
  • Boosts input from 0.5V to stable 3V
  • Features true shutdown capability
  • Offers 70%-90% efficiency
  • Supports input currents up to 1.2A
  • Includes thermal shutdown protection

The Pololu 3.3V Step-up Voltage Regulator U1V11F3 is a compact switching regulator designed to efficiently boost input voltages as low as 0.5 V to a stable 3 V output. It features a true shutdown capability, allowing complete power disconnection from the load, and automatically switches to a linear down-regulation mode when the input voltage exceeds the output.

This regulator is ideal for powering 3 V electronics from various battery types, including NiMH, NiCd, or lithium-ion cells. It offers high efficiency, typically ranging from 70% to 90%, and supports input currents up to 1.2 A. The device includes thermal shutdown protection to prevent overheating.

  • 4x1 Straight male header strip
  • 4x1 Right-angle male header strip
  • 12 x 15 x 3 mm (0.45 x 0.6 x 0.1")
  • Input voltage range: 0.5 V to 5 V
  • Fixed 3 V output with 4% accuracy
  • True shutdown option to turn off power to the load
  • Automatic linear down-regulation when input voltage exceeds output voltage
  • 1.2 A switch supports input currents up to 1.2 A
  • Efficient at light load with typical no-load quiescent current under 1 mA
  • Integrated over-temperature shutoff
