TPS61023 5V Mini-Booster Adafruit TPS61023 5V Mini-Booster is designed to provide a 5V output power supply and up to 1A current. This mini booster comes with feedback resistors set to give 5.2V, which becomes 5V after the voltage drops over the cables. The TPS61023 is a thermally efficient chip that integrates dual 3A MOSFET switches. This mini-booster operates at ±2.5% reference voltage accuracy over the -40°C to +125°C temperature range. The TPS61023 mini-booster is used with battery-powered projects with 2 or 3 Alkaline or a single Lithium battery.
