The Toshiba TCR3DF31 is a fixed 3.1V LDO regulator delivering 300mA. With a dropout of 0.27V and PSRR of 70dB, it ensures stable, low-noise power for various portable applications. The SMV package supports compact designs.
- Low dropout (0.27V) enables operation from tight voltage margins.
- 70dB PSRR at 1kHz reduces supply noise.
- 300mA output current is versatile for many loads.
- SMV package minimizes board space.
3.3V to 3.1V Conversion
When a system has a 3.3V rail but needs 3.1V for a specific IC, this LDO provides a simple solution with only 0.2V headroom, thanks to its low dropout.
Battery-Powered GPS Modules
GPS receivers often require a stable 3.1V supply. The 300mA output supports acquisition and tracking currents, while PSRR reduces interference.
Portable Gaming Consoles
For handheld gaming, the regulator powers the main SoC at 3.1V, maintaining performance during battery voltage drops.
Wireless Charging Receivers
In Qi receivers, this LDO regulates the rectified voltage to 3.1V for the control circuitry, ensuring reliable communication.
Smart Watches
The compact SMV package and low dropout make it suitable for powering the display driver and sensors in smartwatches.
Industrial Sensors
For 4-20mA loop-powered sensors, the low dropout allows operation from a 3.3V supply with minimal loss.
