TPS7A8500RGRR TI High Precision Low Noise LDO Regulator
TPS7A8500RGRR is a high-performance ultra-low-noise positive linear LDO regulator from Texas Instruments, packaged in 20-pin VQFN surface-mount housing with exposed thermal pad for superior heat dissipation, shipped on tape-and-reel with RoHS compliance and MSL1 rating for high-volume SMT manufacturing. It supports an input voltage range from 2.2V up to 5.7V and delivers adjustable output voltage from 0.8V to 5.5V with up to 4A continuous output current capacity, operating reliably across a commercial temperature span of 0°C to +125°C junction temperature. Designed for noise-sensitive high-speed analog and RF circuits, this LDO achieves ultra-low output noise of just 4.4µV RMS across 10Hz to 100kHz bandwidth, alongside exceptional power supply rejection ratio (PSRR) to suppress switching ripple from upstream DC-DC converters.
TI LDO Regulator Features AND Applications
This premium LDO integrates a precision bandgap reference with tight 0.5% initial output voltage accuracy and minimal temperature drift, equipped with programmable soft-start circuitry to limit inrush current during power-up and prevent supply rail voltage sag. It includes comprehensive built-in protection mechanisms: thermal shutdown, cycle-by-cycle current limiting, reverse current protection, and undervoltage lockout to safeguard the device and downstream loads under fault conditions. A dedicated noise reduction pin allows connection of an external capacitor to further suppress output noise, while high PSRR performance above 60dB at frequencies below 1MHz ensures clean power for sensitive high-frequency components. The exposed pad QFN structure delivers low thermal resistance, enabling stable full-load operation without bulky external heat sinks, and an enable pin provides simple on/off control for system power sequencing and low-power standby modes.
It serves as a premium clean power supply IC for RF transceivers, high-speed FPGA and ASIC core/analog rails, high-precision test and measurement instruments, medical diagnostic equipment, high-fidelity audio circuits, millimeter-wave radar modules, and optical communication transceiver boards, where ultra-quiet, stable regulated voltage is critical to preserve signal integrity and measurement accuracy in noise-critical embedded systems.
Alternative linear power ICs
● TPS7A8500RGRT (TI): Identical electrical specification QFN-20 device with shorter tape reel length, offering direct pin-to-pin drop-in PCB replacement during stock shortages.
● LT3085EFE (Analog Devices): 4A low-noise adjustable LDO with comparable noise performance and thermal packaging as cross-brand high-precision second-source option.
● APL5154 (Anpec): Cost-effective 4A adjustable LDO with basic protection circuits for budget industrial power supply redesign substitution.
