Boardoza TPS70302 Dual Output Voltage Regulator Breakout Board
The Boardoza TPS70302 Dual Output Voltage Regulator Breakout Board is a compact and efficient power regulation solution based on the Texas Instruments TPS70302 dual low-dropout linear regulator. Designed for modern embedded and low-power applications, this module provides two stable output rails from a single input supply — making it ideal for systems requiring split-voltage operation. With an input voltage range of 4.3V to 6V, the board delivers 3.3V fixed from the first output and a selectable 1.2V or 1.8V from the second output. The device’s low dropout voltage, high accuracy, and built-in protection features ensure excellent performance for powering microcontrollers, digital ICs, FPGAs, and precision analog components.

Key Features
- Dual Regulated Outputs: Provides 3.3V fixed and selectable 1.2V or 1.8V outputs.
- High Accuracy: ±2% output accuracy across load and temperature variations.
- Integrated Power-On Reset: 120 ms delay ensures stable system startup.
- Comprehensive Protection: Features thermal shutdown and undervoltage lockout (UVLO).
- Efficient Split-Supply Design: Ideal for powering both analog and digital circuitry.
