Categories: Linear, Low Drop Out (LDO) Regulators
Quality Control: Learn More
The Texas Instruments LP3855ET-1-8 is a positive fixed voltage linear regulator designed for applications requiring stable 1.8V output with a 1.5A capability. This device features an enable pin for control and offers robust protection against over current, over temperature, and short circuit conditions. With a low quiescent current of 3 mA and a maximum input voltage of 7V, it is suitable for power-sensitive designs. The LP3855ET-1-8 boasts a high Power Supply Rejection Ratio (PSRR) ranging from 73dB to 57dB across a 120Hz frequency range. Its dropout voltage is a nominal 0.38V at full 1.5A load, ensuring efficient operation. Supplied in a TO-220-5 package for through-hole mounting, this regulator is commonly implemented in industrial, automotive, and telecommunications systems.
