TITPS7A0233PYCHR
Overview
The TPS7A0233PYCHR is an ultra-low-power, 200mA low-dropout (LDO) linear regulator designed specifically for power-sensitive applications. It features a remarkably low typical quiescent current (Iq) of 25nA, making it ideal for extending battery life in always-on devices. This 3.3V fixed-output regulator is housed in a tiny 4-pin DSBGA package, measuring only 0.64mm by 0.64mm.
Why Choose This Part
The primary advantage is the 25nA quiescent current, which is significantly lower than standard low-power LDOs. It maintains high 1.5 percent accuracy across its operating temperature range while requiring no external pulldown resistor for the enable pin due to its smart enable logic. The DSBGA package provides an extremely small footprint for high-density layouts.
Applications
Key Specifications
Getting Started
To evaluate this IC, look for the TPS7A02 evaluation module (EVM) from Texas Instruments. Ensure your PCB design accounts for the extremely small 0.35mm pitch of the DSBGA package, which may require high-density interconnect (HDI) manufacturing. Use low-ESR ceramic capacitors close to the IN and OUT pins to ensure stability and optimal transient response.
