Adafruit 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 that are set to give 5.2V which becomes 5V after the voltage drop 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 -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.
