TPS78618KTTT Description

Short technical summary and product information.

The Texas Instruments TPS78618KTTT is a 1.5A low-dropout linear voltage regulator (LDO) designed for noise-sensitive applications. It offers ultralow noise, high power-supply rejection ratio (PSRR), and excellent line and load transient responses.

 

This regulator provides a fixed 1.8V output voltage and can deliver up to 1.5A of current. Key electrical characteristics include a very low dropout voltage of 390mV at full load, a typical quiescent current of 265µA, and a fast start-up time of 50µs. The device also features high PSRR of 49dB at 10kHz and ultralow noise of 48µVRMS.

 

Designed for surface mounting, the TPS78618KTTT is available in a DDPAK/TO-263-5 package. It includes protection features such as over current, over temperature, reverse polarity, and under voltage lockout (UVLO). The enable control feature allows for easy power management.

 

Applications benefiting from its performance include RF circuits like VCOs and receivers, audio systems, and wireless communication devices such as Bluetooth and WLAN modules.
