TPS78618DCQR Description

Short technical summary and product information.

The Texas Instruments TPS78618DCQR is a high-performance, low-dropout (LDO) linear voltage regulator designed for demanding applications. It provides a stable 1.8V output voltage with a maximum output current of 1.5A. This regulator family is known for its ultralow noise (48 μVRMS) and high Power Supply Rejection Ratio (PSRR), with values up to 49 dB at 10 kHz, ensuring clean power delivery for sensitive analog and RF circuits.

 

The TPS78618DCQR features excellent load and line transient responses and a fast start-up time of 50 μs. It operates over a wide temperature range of -40°C to 125°C and includes protection features such as over current, over temperature, reverse polarity, and under voltage lockout (UVLO).

 

This device is supplied in a SOT-223-6 surface-mount package, requiring minimal board space. Its stability with a 1-μF ceramic capacitor on the output simplifies design and component selection. The TPS786 family is ideal for applications including RF systems, audio circuits, and portable electronics where noise and power efficiency are critical.
