TPS7A8801RTJR LDO voltage regulator
The TPS7A8801RTJR from Texas Instruments is a high-performance, dual-channel low-dropout (LDO) voltage regulator designed to deliver ultra-low noise and high power supply rejection (PSR) for sensitive analog and RF circuits. Each channel is independently controlled and can provide an output current of up to 2 A from an input voltage range of 1.4 V to 6.5 V, with a very low dropout voltage of only 125 mV at 2 A. It achieves an exceptionally low output noise of 4.6 µVRMS (10 Hz to 100 kHz) and a high PSR of 70 dB at 1 MHz, making it an ideal power solution for noise-critical applications such as high-speed data converters, RF transceivers, and precision instrumentation.
TPS7A8801RTJR LDO regulator Core Features
The architecture of the TPS7A8801RTJR incorporates advanced design techniques to minimize noise and maximize PSR. Each channel features an internal reference, error amplifier, and power FET, with independent enable, feedback, and soft-start control. Key features include programmable output voltage via an external resistor divider, power-good indicators for each channel, and programmable current limit. The device includes a bias supply pin that allows the internal control circuitry to be powered from a cleaner, lower-voltage rail, further enhancing noise performance and efficiency. Its wide bandwidth error amplifier ensures excellent transient response to sudden load changes.
