Categories: Linear, Low Drop Out (LDO) Regulators
Quality Control: Learn More
The STMicroelectronics L7818ABV is a positive, fixed linear voltage regulator offering an 18V output and a 1.5A maximum output current. This TO-220AB packaged device features over-temperature and short-circuit protection. With a guaranteed output current of 1.5A and a typical dropout voltage of 2V at 1A, it is suitable for a wide input voltage range up to 35V. Its high PSRR of 59dB at 120Hz contributes to robust power supply filtering. Applications include automotive, industrial, and consumer electronics requiring stable voltage regulation. The device operates across a temperature range of -40°C to 125°C.
