The MCP1825S-1802E/EB is a fixed 1.8V low dropout linear regulator from Microchip Technology, rated for 500mA output. With a dropout voltage of just 0.35V at full load and a quiescent current of 220 µA, it is optimized for power-sensitive applications. The DDPAK-3 package ensures robust thermal dissipation in compact designs.
- Stable 1.8V Rail: Ideal for modern low-voltage digital cores and I/O.
- 500mA Current Capacity: Handles moderate loads without external pass transistors.
- Low Dropout: 0.35V at 500mA enables efficient conversion from 2.5V or 3.3V inputs.
- Low Quiescent Current: 220 µA reduces standby power in battery devices.
FPGA Core Supplies
Modern FPGAs often require a 1.8V core rail. The MCP1825S-1802E/EB delivers 500mA with low dropout, ensuring stable operation from a 2.5V or 3.3V source.
DSP and Microcontroller I/O
Many DSPs and MCUs use 1.8V I/O. This regulator provides a clean, low-noise supply for mixed-signal processing.
Portable Medical Devices
Low quiescent current (220 µA) and small DDPAK-3 package make it suitable for battery-powered glucose meters and pulse oximeters.
Wireless Modules
For Bluetooth and Zigbee modules requiring 1.8V logic, this LDO offers good PSRR (60dB at 100Hz) to reject RF interference.
