The RS3221-3.3YF5 is a fixed 3.3V low dropout linear regulator capable of delivering 200mA of output current. Housed in a compact SOT-23-5 package, it features a low dropout voltage of 0.16V at full load, making it suitable for battery-operated applications. With PSRR ranging from 48dB to 36dB across 217Hz to 1kHz, it provides clean power for noise-sensitive circuits.
- Low Dropout Voltage: 0.16V at 200mA maximizes efficiency in battery-powered designs by allowing operation closer to the battery's end-of-life voltage.
- Compact SOT-23-5 Package: Saves PCB space for space-constrained portable and IoT applications.
- Good PSRR Performance: 48dB to 36dB (217Hz-1kHz) reduces power supply noise, improving analog and RF circuit performance.
- Fixed 3.3V Output: Simplifies design with a stable, predefined output voltage requiring no external resistor divider.
Portable Battery-Powered Devices
The 200mA output and low 0.16V dropout at full load make it ideal for extending battery life in handheld devices, ensuring stable 3.3V rail even as battery voltage declines.
Noise-Sensitive Analog Circuits
