TLV1117-18IDCY

TLV1117-18IDCY Description

The TLV1117-18IDCY from Texas Instruments is a fixed-output, low-dropout (LDO) linear voltage regulator designed to deliver a stable 1.8V output at up to 800mA of continuous current. With a 15V maximum input voltage, this regulator is optimized for applications requiring efficient power management in space-constrained environments. Housed in a SOT-223-4 surface-mount package, it offers robust thermal performance and ease of integration. The device features a low dropout voltage of 1.3V (max) at 800mA, ensuring reliable operation even with minimal headroom. Its 75dB PSRR (120Hz) minimizes noise, making it suitable for sensitive analog and digital circuits.
