TLV1117LV18DCYT Description

Short technical summary and product information.

The Texas Instruments TLV1117LV18DCYT is a low-dropout (LDO) linear voltage regulator offering a fixed 1.8V output at up to 1A. This device is a low input voltage version of the popular TLV1117 series, designed for power-sensitive applications with its low quiescent current of 100 µA maximum.

 

Key electrical specifications include an input voltage range of 2V to 5.5V, a typical dropout voltage of 455 mV at 1A (for a 3.3V output), and a minimum specified current limit of 1.1A. It also boasts a high Power Supply Rejection Ratio (PSRR) of 65 dB at 1 kHz and typical accuracy of 1.5%.

 

For thermal management, the TLV1117LV18DCYT operates within a temperature range of -40°C to 125°C and includes built-in thermal shutdown and overcurrent protection features. The regulator is stable with cost-effective ceramic capacitors and is supplied in a 4-pin SOT-223 (DCY) surface-mount package.

 

This LDO regulator is suitable for various power management applications where a stable, low-voltage supply is required. Its compact package and robust protection features make it a versatile choice for designs needing reliable voltage regulation.
