The TPS7H1111 is an ultra-low noise, high PSRR, low dropout linear regulator (LDO) optimized for powering radio-frequency (RF) devices in a space environment. The device can source up to 1.5 A over a 0.85-V to 7-V input range with a 2.2-V to 14-V bias supply. The high performance of the device limits power supply, generated phase noise, and clock jitter, making this device an option for powering high-performance ADCs, DACs, VCOs, PLLs, SerDes, and other RF components in satellites. For digital loads (such as FPGAs and DSPs) requiring low voltage operation, the accuracy and transient performance is designed for system performance.
