LF18CV
IC REG LINEAR 1.8V 500MA TO220ABManufacturer: STMicroelectronics
Categories: Linear, Low Drop Out (LDO) Regulators
Quality Control: Learn More
The STMicroelectronics LF18CV is a positive fixed output linear voltage regulator IC. This component provides a stable 1.8V output with a maximum output current of 500mA. It features a low quiescent current of 1mA and a maximum input voltage rating of 16V. The LF18CV offers robust protection against over current and over temperature conditions. Its power supply rejection ratio (PSRR) ranges from 82dB to 60dB across a frequency band of 120Hz to 10kHz, ensuring clean power delivery. Designed for through-hole mounting, the LF18CV is supplied in a TO-220-3 package. This regulator is suitable for applications in automotive, industrial, and consumer electronics where reliable voltage regulation is critical. The dropout voltage is typified at 0.7V at 200mA.
