Linear & Switching Voltage Regulators

TPS72518DCQ Description

The TPS72518DCQ from Texas Instruments is a high-performance, fixed-output 1.8V, 1A low-dropout (LDO) linear voltage regulator in a SOT-223-6 package. Designed for precision power management, it features a 6V maximum input voltage and a low dropout voltage of 0.32V @ 1A, ensuring efficient operation even with tight input-output differentials. With a quiescent current of 225 µA and a supply current of 325 µA (max), it is optimized for power-sensitive applications. The device includes enable/reset control and robust protection features such as over-current, over-temperature, reverse polarity, and under-voltage lockout (UVLO), making it highly reliable in demanding environments.

TPS72518DCQ Features

• Fixed 1.8V Output: Ensures stable voltage regulation for sensitive loads.
• High PSRR (60dB @ 1kHz): Minimizes noise for clean power delivery.
• Low Dropout (0.32V @ 1A): Maximizes efficiency in low-input scenarios.
• 1A Output Current: Supports high-current applications.
• Advanced Protection: Includes over-current, over-temperature, reverse polarity, and UVLO.
• Enable/Reset Control: Allows for power sequencing and system management.
