The RT9166A-25GXL from Richtek is a fixed 2.5V LDO regulator capable of delivering up to 600mA. With a typical dropout voltage of only 0.58V at full load and 55dB PSRR at 1kHz, it provides efficient and clean power for a variety of applications. The SOT-89-3 package ensures good thermal performance for higher current operation.
- High Output Current: 600mA capability supports power-hungry loads like FPGAs and wireless modules.
- Low Dropout Voltage: 0.58V typical at 600mA maximizes efficiency in low-headroom designs.
- Good Thermal Performance: SOT-89-3 package with exposed pad dissipates heat effectively.
- Stable 2.5V Output: Fixed output ideal for logic and mixed-signal circuits.
High-Current Portable Devices
With 600mA output capability, this regulator can power higher-current loads such as GPS modules, Bluetooth SoCs, and small motors in portable devices.
Post-Regulation for Switching Converters
The low dropout of 0.58V at full load makes it ideal for cleaning up noisy DC-DC converter outputs, providing a stable 2.5V rail.
FPGA and CPLD Core Supply
Many low-power FPGAs require 2.5V core supplies with up to 500mA; this LDO provides sufficient current with good regulation.
Automotive Infotainment
The SOT-89-3 package offers good thermal dissipation for higher current loads in car audio and infotainment systems.
Industrial Sensors
Reliable 2.5V output with 55dB PSRR at 1kHz makes it suitable for industrial pressure, temperature, and flow sensors.
