The MP8801DJ-2.5-LF-Z is a fixed 5V output LDO linear regulator from Monolithic Power Systems, delivering up to 150mA with a typical dropout of just 0.125V. Its low 150 µA quiescent current and high PSRR of 70dB at 1kHz make it suitable for noise-sensitive portable and industrial applications. Housed in a compact TSOT-23-5 package, this regulator offers a practical solution for space-constrained designs requiring stable voltage conversion.
- Extended Battery Life: The 150 µA quiescent current minimizes standby power draw, ideal for battery-operated devices.
- Clean Output: 70dB PSRR at 1kHz effectively rejects input noise, ensuring stable operation for analog and RF circuits.
- High Efficiency at Low Dropout: 0.125V dropout at 150mA reduces power dissipation, improving thermal performance in compact layouts.
- Compact Footprint: TSOT-23-5 package saves PCB space without compromising output current capability.
Battery-Powered IoT Sensors
The low 150 µA quiescent current and 0.125V dropout at 150mA make it ideal for extending battery life in wireless sensor nodes, where the regulator maintains a stable 5V rail as the battery voltage declines.
Portable Medical Devices
With a PSRR of 70dB at 1kHz, this LDO effectively filters switching noise from upstream DC-DC converters, ensuring clean power for sensitive analog front-ends in glucose monitors and pulse oximeters.
Wearable Electronics
The compact TSOT-23-5 package and 150mA capability suit space-constrained wearables like smartwatches, providing a regulated 5V supply for display drivers and haptic actuators.
Industrial Sensor Interfaces
The wide input range down to 1.25V allows operation from multi-cell battery stacks or energy harvesting circuits, delivering a stable 5V reference for 4-20mA loop transmitters.
RF Transceiver Modules
The 70dB PSRR at 1kHz and 30dB at 1MHz suppresses power supply noise that could otherwise degrade RF signal integrity in Bluetooth and Zigbee modules.
Automotive Infotainment Backup
For always-on backup systems, the low dropout ensures the 5V rail remains regulated even during cold-crank conditions where the input voltage dips significantly.
