Quality Control: Learn More
Texas Instruments LP38856T-1-2 is a positive fixed linear voltage regulator designed for high-current applications. This device provides a stable 1.2V output with a maximum output current capability of 3A. Featuring a low dropout voltage of 0.45V at 3A, it ensures efficient operation even under demanding load conditions. The regulator includes comprehensive protection mechanisms such as over-current, over-temperature, short-circuit, and under-voltage lockout (UVLO). It operates over a wide temperature range of -40°C to 125°C and is supplied in a TO-220-5 package. The device also offers an enable pin for output control and exhibits excellent power supply ripple rejection (PSRR) ranging from 80dB to 65dB between 120Hz and 1kHz. Typical applications include power supplies for base stations, automotive systems, and industrial equipment.
