The MCP1826S-3302E/DB from Microchip Technology is a 1A low-dropout linear regulator with a fixed 3.3V output. Its 0.4V dropout at full load allows operation from 3.7V Li-ion or 5V USB sources. The 220µA quiescent current balances efficiency with performance. The SOT-223-3 package offers excellent thermal resistance for continuous 1A operation. With 60dB PSRR at 100Hz, it delivers clean power for sensitive analog and digital circuits.
- High current capacity: 1A output in a compact SOT-223 package, suitable for power-hungry peripherals.
- Low dropout: 0.4V at 1A enables efficient conversion from 3.7V batteries or 5V rails.
- Good PSRR: 60dB at 100Hz rejects mains ripple, ensuring clean 3.3V for audio and RF circuits.
- Thermal efficiency: SOT-223 package dissipates heat effectively, reducing the need for heatsinks.
FPGA/CPLD Core Power
With 1A output and 0.4V dropout, the MCP1826S powers 3.3V I/O banks or 1.8V cores (via adjustable version) from a 5V USB supply with minimal heat generation.
USB Peripheral Power
This LDO regulates 5V USB bus power down to 3.3V for Wi-Fi modules, sensors, and SD cards. The SOT-223 package handles the thermal load of 1A continuous draw.
Networking Equipment
In routers and switches, it provides clean 3.3V for PHY chips and switch ICs. The 60dB PSRR at 100Hz filters out 50/60Hz hum from AC-DC adapters.
Battery-Powered Devices
For 3.7V Li-ion batteries, the 0.4V dropout allows the regulator to deliver 3.3V until the battery reaches 3.7V, maximizing usable capacity.
Industrial Sensors
The low dropout and 1A capability power multiple 3.3V sensors from a 5V industrial rail, with stable output for precision analog measurements.
Set-Top Boxes
Provides 3.3V for tuner and demodulator circuits, with the PSRR ensuring clean power in noisy consumer environments.
