The 2119-POLOLU is a S7V7F5 switching step-up/step-down regulator efficiently produces 5 V from input voltages between 2.7 and 11.8 V.

Its ability to convert both higher and lower input voltages makes it useful for applications where the power supply voltage can vary greatly, as with batteries that start above but discharge below 5 V. The very compact (0.35″ × 0.475″) module can supply up to 1 A when stepping down and about 500 mA when stepping up.

Features

  • input voltage: 2.7 to 11.8 V
  • fixed  5V output with +5/-2% accuracy
  • typical continuous output current: 1 A when stepping down; 500 mA when stepping up (Actual continuous output current depends on input voltage. See Typical Efficiency and Output Current section below for details)
  • power-saving feature maintains high efficiency at low currents
  • integrated over-temperature protection
  • small size: 0.35″ × 0.475″ × 0.1″ (9 × 12 × 3 mm)

Dimensions

  • Size: 0.35″ × 0.475″ × 0.1″

General specifications

  • Minimum operating voltage: 2.7 V
  • Maximum operating voltage: 11.8 V
  • Maximum output current: 1 A²
  • Default output voltage: 5 V
  • Reverse voltage protection?: N
