Quality Control: Learn More
Texas Instruments LP38859T-1-2 is a positive fixed output linear voltage regulator IC, delivering a stable 1.2V at up to 3A. This TO-220-5 packaged component features a low dropout voltage of 0.45V at 3A, ensuring efficient power delivery. Key control features include soft start for controlled power-up sequences. Protection mechanisms are integrated, encompassing over-current, over-temperature, short-circuit, and under-voltage lockout (UVLO) to safeguard the system. The device exhibits a high Power Supply Rejection Ratio (PSRR) of 80dB to 65dB across a 120Hz to 1kHz frequency range, making it suitable for applications sensitive to power supply noise. With an input voltage range up to 5.5V and an operating temperature range of -40°C to 125°C, the LP38859T-1-2 finds application in various demanding sectors including automotive, industrial automation, and telecommunications.
