Typical Applications
TPS7A8300RGRR is suitable for 6 applications: RF Transceiver Power Supply, Audio DAC Power Supply, FPGA Core Voltage, Industrial Sensor Interface, Battery-Powered Devices, Test and Measurement Equipment.
RF Transceiver Power Supply
The TPS7A8300RGRR provides a clean, low-noise supply for RF transceivers, ensuring minimal phase noise and spurious emissions. Its 6 µV RMS noise and high PSRR reduce interference in the signal chain, while the 2A output current supports high-power transmitters. The low dropout voltage allows operation from a 3.3V rail with headroom for battery sag.
Recommended
Audio DAC Power Supply
The TPS7A8300RGRR is ideal for powering audio DACs and op-amps, where noise directly impacts dynamic range and THD. Its 6 µV RMS noise and high PSRR ensure a clean supply, while the programmable output voltage (0.8V to 5V) accommodates various DAC rails. The low dropout voltage minimizes power dissipation in portable audio devices.
Recommended
FPGA Core Voltage
The TPS7A8300RGRR provides a stable, low-noise core voltage for FPGAs, which require tight voltage regulation and high current. Its 2A output current supports many mid-range FPGAs, while the programmable output voltage (e.g., 1.0V, 1.2V) matches core requirements. The power-good indicator simplifies power sequencing.
Recommended
Industrial Sensor Interface
The TPS7A8300RGRR powers precision sensors and ADCs in industrial applications, where noise and accuracy are critical. Its low noise and high PSRR ensure accurate measurements, while the wide input voltage range (1.1V to 6.5V) accommodates various supply rails. The enable pin allows power cycling for power saving.
Recommended
Battery-Powered Devices
The TPS7A8300RGRR is suitable for battery-powered devices due to its low quiescent current (50 µA) and low dropout voltage. It efficiently regulates from a battery voltage down to the required output, extending battery life. The small VQFN package saves board space in portable designs.
Recommended
Test and Measurement Equipment
The TPS7A8300RGRR provides clean, stable power for test and measurement equipment, where precision and low noise are paramount. Its low noise and high PSRR ensure accurate measurements, while the programmable output voltage allows flexible supply rails. The power-good indicator aids in system monitoring.

Key Differentiators
- Higher output current (2A) compared to alternatives (vs ADM7150ARDZ)
- Programmable output via ANY-OUT pins without external resistors (vs TPS7A4700RGWR)
- Power-good indicator (vs LT3045EDC)
Design Notes
The TPS7A8300RGRR can dissipate significant power at high input-output differentials. For example, at VIN=5V, VOUT=1.2V, and 2A load, power dissipation is 7.6W. The VQFN-20 package has a thermal resistance of 40°C/W, resulting in a 304°C junction temperature rise. A heatsink or large copper area is required for reliable operation above 2W dissipation.
Place input and output capacitors as close to the IC pins as possible. Use a 10µF ceramic capacitor on the input and a 10µF ceramic capacitor on the output. Add a 0.1µF ceramic capacitor in parallel for high-frequency noise bypass. The ANY-OUT pins should be connected to GND or left open according to the desired output voltage.
Do not exceed the maximum input voltage of 6.5V. Ensure the ANY-OUT pins are configured correctly to avoid unintended output voltages. The power-good pin is open-drain and requires a pull-up resistor. The enable pin must be driven high to turn on the regulator; do not leave it floating.
Compliance Information
RoHS compliant per TI product page. Not AEC-Q100 qualified - choose TPS7A8300RGRR-Q1 for automotive.
