LF18CDT-TR Description

Short technical summary and product information.

The STMicroelectronics LF18CDT-TR is a linear voltage regulator designed for power management applications. It provides a fixed positive output voltage of 1.8V and can supply up to 500mA of current. The regulator operates with a maximum input voltage of 16V and has a typical voltage dropout of 0.7V at 200mA.

 

Key electrical characteristics include a quiescent current of 1mA and a supply current of up to 12mA. It also offers Power Supply Rejection Ratio (PSRR) ranging from 82dB to 60dB across a frequency range of 120Hz to 10kHz. Protection features include over-current and over-temperature protection.

 

This component is housed in a Surface Mount DPAK package, also known as TO-252-3, DPak (2 Leads + Tab), or SC-63. The operating temperature range is from -40°C to 125°C. The LF18CDT-TR is suitable for various electronic designs requiring stable voltage regulation.
