TLV1117-18CDCY

TLV1117-18CDCY Description

The TLV1117-18CDCY from Texas Instruments is a high-performance, fixed-output 1.8V linear voltage regulator designed for low-dropout (LDO) applications. Capable of delivering up to 800mA of continuous output current, it operates with an input voltage range up to 15V, making it suitable for a variety of power management tasks. The device features a low dropout voltage of 1.3V (max) at 800mA, ensuring efficient regulation even when the input voltage is close to the output level. With a quiescent current of 10mA and excellent 75dB PSRR (120Hz), it minimizes power loss and noise, making it ideal for sensitive analog and digital circuits.
