TPS7A0512PDBZR – TEXAS INSTRUMENTS

The TPS7A0512PDBZR is a low-dropout (LDO) linear regulator from Texas Instruments, packaged in a space-saving 6-pin SOT-23 (PDSO-6) surface-mount package. It provides a fixed 1.2V output voltage with a maximum output current of 150mA. This device boasts a very low quiescent current of only 18µA, making it highly efficient in low-power applications. Its input voltage range spans from 1.8V to 5.5V, allowing for flexible design choices. The TPS7A0512PDBZR incorporates internal overcurrent and thermal protection, enhancing its robustness and reliability. Its low output noise (typically 30µVrms) makes it suitable for sensitive analog circuits. _x000D_

Unlike many LDOs, the TPS7A0512PDBZR features a very low dropout voltage (typically 160mV at 150mA), allowing for efficient regulation even with minimal input-output voltage differentials. This characteristic is particularly advantageous in battery-powered systems where maximizing battery life is critical. Common applications include powering microcontrollers, analog-to-digital converters (ADCs), and other low-power integrated circuits requiring a stable 1.2V supply. The device’s small size and high efficiency contribute to a compact and energy-efficient design.
