Overview

The TPS7A2018PYCKR is an ultra-small, low-dropout (LDO) linear regulator that provides a fixed 1.8V output from an input range of 1.6V to 6.0V. It is specifically designed for space-constrained applications, featuring a tiny 4-DSBGA package and a low quiescent current of 6.5 microamps at no load.

Why Choose This Part

This regulator offers a high 300mA output current capability despite its microscopic 4-DSBGA footprint. It simplifies PCB layout by remaining stable with a single 1 microfarad ceramic output capacitor and eliminates the need for an external noise-bypass capacitor while maintaining low noise performance.

Applications

Battery-Powered Wearables
Extends battery life in devices like smartwatches and fitness trackers due to its low 6.5 microamp quiescent current and low shutdown current.
RF and Wireless Modules
Provides clean power to sensitive RF components with high PSRR of 65dB to 40dB across a wide frequency range up to 1MHz.
Smartphones and Tablets
Ideal for high-density mobile PCBs where the 0.62mm x 0.62mm footprint minimizes board area usage.
Camera Modules
Supplies low-noise power to image sensors without requiring an external noise-bypass capacitor.

Getting Started

When designing with the DSBGA package, ensure precise solder stencil alignment due to the 0.35mm pitch. For evaluation, use the TPS7A20EVM-056 evaluation module to test performance metrics like load transient response and PSRR before finalizing the board layout. Connect a 1 microfarad ceramic capacitor as close as possible to the VOUT and GND pins for stability.
