TPS7A8300RGRR 2A LDO regulator IC Positive Adjustable/Programmable 1 Output
The TPS7A8300RGRR is a high-performance, low-noise, low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver ultra-clean power for sensitive analog and RF applications. This advanced regulator provides a fixed or adjustable output voltage ranging from 0.8V to 3.95V with an impressive output current capability of 2A, making it ideal for powering high-speed data converters, precision amplifiers, and wireless communication modules. The device features an exceptionally low noise performance of 4.7μVRMS (10Hz to 100kHz) and high power supply rejection ratio (PSRR) of 75dB at 1kHz, ensuring stable operation even in noisy environments. Its low dropout voltage of 110mV at 2A maximizes efficiency, particularly in battery-powered systems where every millivolt counts.
Packaged in a compact 20-pin VQFN (RGR) package, the TPS7A8300RGRR integrates multiple protection features including current limit, thermal shutdown, and reverse current protection for robust system reliability. The regulator operates over a wide input voltage range of 1.4V to 6.5V, accommodating various power sources from lithium-ion batteries to regulated DC supplies. Its fast transient response and 1% output voltage accuracy make it particularly suitable for powering noise-sensitive components in medical imaging equipment, test and measurement instruments, and 5G infrastructure. The device also includes an enable pin and power-good indicator for flexible power sequencing and system monitoring.
For applications requiring different specifications, alternative LDO regulators include the TPS7A4700 (1A output, ultra-low noise 4μVRMS), LT3045 (500mA, ultra-high PSRR 79dB), and ADM7154 (800mA, 0.8V-3.95V adjustable output). These alternatives offer varying combinations of current capability, noise performance, and package options to suit different design requirements.
