TPS73801MDCQPSEP

TPS73801MDCQPSEP Description

The TPS73801MDCQPSEP from Texas Instruments is a radiation-tolerant, low-dropout (LDO) voltage regulator designed for high-reliability applications in harsh environments. With an adjustable output range of 1.21V to 20V and a maximum input voltage of 20V, it delivers up to 1A of continuous output current while maintaining exceptional efficiency. The device features a low quiescent current of 1.5 mA and a dropout voltage as low as 0.4V at 1A, making it ideal for power-sensitive systems. Its 63dB PSRR at 120Hz ensures stable performance in noisy environments, while integrated protection features like over-current, over-temperature, and reverse polarity safeguards enhance system reliability.
