TITPS7A0230PDQNR
Overview
The TPS7A0230PDQNR is an ultra-low-power, 200mA linear voltage regulator designed specifically for applications where power consumption is the critical design constraint. It features a fixed 3.0V output and an industry-leading quiescent current of just 25nA, significantly extending battery life in always-on devices. The device is housed in a tiny 1mm x 1mm X2SON package, making it ideal for space-constrained wearable and IoT designs.
Why Choose This Part
The primary advantage is the 25nA quiescent current, which remains low even under dropout conditions, unlike many competing LDOs. It offers a 1.5 percent output accuracy over the full -40C to 125C temperature range, ensuring reliable performance for precision analog rails. Additionally, the integrated smart enable pulldown simplifies circuit design by eliminating the need for external resistors to manage the enable pin state.
Applications
Key Specifications
Getting Started
When designing with this LDO, place a 1uF ceramic capacitor close to the input and output pins to ensure stability across the 200mA load range. The X2SON package requires careful stencil design due to its 1mm x 1mm dimensions and bottom-side thermal pad. For prototyping, use the TPS7A02EVM-050 evaluation module to measure the ultra-low quiescent current and transient response in a controlled environment.
