TPS78618KTTR Description

Short technical summary and product information.

The Texas Instruments TPS78618KTTR is a high-performance, low-dropout (LDO) linear voltage regulator designed for applications requiring low noise and high power supply rejection ratio (PSRR). This device provides a stable 1.8V output voltage with a maximum output current of 1.5A.

 

Key features include ultralow noise (48 µV RMS for the TPS78630 variant), a high PSRR of 49 dB at 10 kHz, and a fast start-up time of 50 µs. The regulator exhibits excellent load and line transient responses and a very low dropout voltage of 390 mV at full load (for the TPS78630 variant). Its quiescent current is typically 265 µA, reducing to less than 1 µA in standby mode.

 

The TPS78618KTTR is available in a TO-263-6, D²Pak (5 Leads + Tab), TO-263BA package, suitable for surface mounting. This makes it a versatile choice for RF applications, audio circuits, wireless communication devices, and handheld organizers where space and performance are critical.

 

Protection features include over current, over temperature, reverse polarity, and under voltage lockout (UVLO), enhancing system reliability.
