The Microchip MCP1804 is a fixed-output LDO linear regulator delivering 1.0V at up to 150mA. It accepts input voltages up to 12V, making it versatile for multi-rail systems. With a low 115 µA quiescent current and 0.85V dropout at full load, it balances efficiency and stability. The SOT-89-5 package offers a compact footprint for space-limited designs. Its 50dB PSRR at 1kHz helps reject power supply noise, ensuring clean output for sensitive loads.
- Extended Battery Life: Ultra-low 115 µA quiescent current minimizes standby drain, ideal for battery-powered devices.
- Wide Input Flexibility: Supports up to 12V input, allowing direct use in automotive and industrial 12V systems without pre-regulation.
- Stable Low-Voltage Output: Fixed 1.0V output with 0.85V dropout at 100mA ensures reliable operation for low-voltage digital cores.
- Noise Rejection: 50dB PSRR at 1kHz filters switching noise, providing clean power for analog and RF circuits.
Battery-Powered IoT Sensors
With a low 115 µA quiescent current and 150mA output, the MCP1804 is ideal for always-on IoT sensor nodes that require minimal standby power while maintaining a stable 1.0V rail for low-voltage MCUs.
Automotive Body Electronics
The 12V input rating allows direct connection to automotive battery lines (with appropriate protection). The 0.85V dropout at 100mA ensures stable operation even during cold-crank conditions where the battery voltage dips.
Industrial Control Modules
In 24V-to-12V industrial systems, this LDO can step down to 1.0V for logic cores. The 50dB PSRR at 1kHz filters out switching noise from adjacent DC-DC converters, ensuring clean power for sensitive analog circuits.
Portable Medical Devices
The SOT-89-5 package and low quiescent current make it suitable for wearable glucose monitors or hearing aids, where PCB area and battery life are critical. The fixed 1.0V output matches low-voltage DSP cores.
Smart Home Hubs
For always-plugged smart speakers or hubs, the MCP1804 provides a clean 1.0V rail for the main processor. Its thermal performance in SOT-89-5 handles continuous 150mA loads without excessive heating.
LED Driver Bias Supplies
Use the MCP1804 to bias LED driver ICs that require a precise 1.0V reference. The 12V input tolerance simplifies power distribution from a common 12V bus, while the low dropout ensures regulation even with marginal input margins.
