IC REG LINEAR 3.3V 500MA TO220Manufacturer: STMicroelectronics
Categories: Linear, Low Drop Out (LDO) Regulators
Quality Control: Learn More
STMicroelectronics LF33ABV-DG is a positive fixed output linear voltage regulator IC. This component offers a stable 3.3V output with a maximum output current capability of 500mA. Designed for through-hole mounting in a standard TO-220-3 package, it operates across a wide temperature range of -40°C to 125°C. Key protection features include over-current and over-temperature shutdown. The device exhibits excellent power supply rejection ratio (PSRR) ranging from 80dB at 120Hz down to 65dB. Input voltage can be as high as 16V, with a typical dropout voltage of 0.7V at the maximum output current. This regulator is suitable for applications in industrial automation, consumer electronics, and telecommunications.
