LF18CDT Description

Short technical summary and product information.

The STMicroelectronics LF18CDT is a linear voltage regulator designed for low-power applications. It features a fixed 1.8V output voltage and can supply up to 500mA of current. The regulator has a very low dropout voltage of 0.7V at 200mA and a low quiescent current of 1mA, making it suitable for battery-powered systems.

 

This device operates over a temperature range of -40°C to 125°C and has a maximum input voltage of 16V. Protection features include over-current and over-temperature protection. The LF18CDT is available in a TO-252-3, DPak (2 Leads + Tab), SC-63 package, suitable for surface mounting.

 

Key electrical characteristics include a PSRR of 82dB ~ 60dB (120Hz ~ 10kHz). The regulator requires minimal external components for stability, making it a space-saving solution. Its design is particularly well-suited for applications requiring stable voltage regulation with low noise and low power consumption.
