TPS79912DDCR – TEXAS INSTRUMENTS

The TPS79912DDCR is a low-dropout (LDO) linear regulator from Texas Instruments, packaged in a space-saving 4-pin WSON (WCSP-4) package. It offers a fixed 1.2V output voltage with a maximum output current of 150mA, making it suitable for applications requiring a precise and stable low-voltage supply. Its input voltage range spans from 1.8V to 5.5V, enabling flexibility in system design. The device features a low quiescent current of typically 70µA, contributing to high efficiency, particularly beneficial in battery-powered systems._x000D_

Key specifications include a maximum output voltage ripple and noise of 20µVrms, ensuring clean power delivery for sensitive circuits. Its thermal shutdown and overcurrent protection mechanisms safeguard against potential damage. The TPS79912DDCR excels in applications requiring a low-noise, highly regulated 1.2V supply for microcontrollers, analog-to-digital converters (ADCs), or other voltage-sensitive components. Its small footprint and low power consumption make it ideal for portable and space-constrained designs where minimizing power loss and board area are critical. The absence of external compensation components simplifies design and reduces BOM cost.
