The MCP1825ST-3002E/DB from Microchip Technology is a fixed 3.0V low dropout linear regulator capable of delivering 500mA. Its low 220 µA quiescent current and 0.35V dropout at full load make it highly efficient for battery-operated systems. The SOT-223-3 package offers excellent thermal performance, while the 60dB PSRR at 100Hz ensures clean output for noise-sensitive analog circuits. This regulator is a reliable choice for portable, industrial, and automotive power management.
- High Efficiency in Battery Systems: The 220 µA quiescent current minimizes standby power drain, extending battery runtime in portable devices.
- Low Dropout Voltage: A 0.35V dropout at 500mA allows operation from a 3.3V rail with ample headroom, reducing heat generation.
- Excellent Ripple Rejection: 60dB PSRR at 100Hz filters out power-supply noise, ideal for precision analog and RF circuits.
- Robust Thermal Package: The SOT-223-3 package dissipates heat effectively, supporting full 500mA output across a wide temperature range.
Battery-Powered Portable Devices
The low 220 µA quiescent current and 500mA output make it ideal for extending battery life in handheld instruments, wireless sensors, and portable medical devices while providing a stable 3.0V rail.
FPGA and DSP Core Supplies
With a dropout of only 0.35V at full load, the MCP1825ST-3002E/DB efficiently steps down from a 3.3V or 3.6V rail to a clean 3.0V core supply, minimizing power dissipation in high-performance logic.
Automotive Infotainment Systems
The wide input range and robust SOT-223 package suit automotive environments, powering microcontrollers and sensors that require a regulated 3.0V supply from a 5V or battery-backed bus.
Industrial Sensor Interfaces
Its 60dB PSRR at 100Hz rejects low-frequency ripple from switching pre-regulators, ensuring accurate analog measurements in factory automation and process control loops.
Networking Equipment
Used in routers and switches to power PHY transceivers and control logic, the LDO provides a low-noise 3.0V output with excellent line and load transient response.
LED Driver Bias Supplies
The 500mA capability can bias LED driver ICs and their control circuits, maintaining a constant 3.0V even when the input sags during high-current pulses.
