The MIC5255-3.0YML-TR is a fixed 3.0V low dropout linear regulator from Microchip Technology, delivering up to 150mA with a low dropout voltage of 0.25V. Its 150µA quiescent current and excellent PSRR make it suitable for battery-powered and noise-sensitive applications. Housed in a compact 6-DFN (2x2) package, it offers a space-saving solution for portable electronics.

  • Low quiescent current (150µA) extends battery life in portable devices.
  • High PSRR (60dB-50dB) ensures clean output for analog circuits.
  • Compact 2x2mm DFN package saves PCB space.
  • Low dropout (0.25V) allows operation with minimal headroom.

Battery-Powered Portable Devices

The 150mA output and low 150µA quiescent current make it ideal for extending battery life in wearables, remote controls, and portable sensors.

Noise-Sensitive Analog Circuits

With PSRR of 60dB to 50dB (10Hz-10kHz), it effectively filters power supply noise for precision op-amps and ADCs.

3V Logic Supply

Provides a stable 3.0V rail for microcontrollers, memory, and digital logic requiring accurate voltage regulation.

Compact IoT Modules

The 2x2mm DFN package suits space-constrained designs like smart sensors and wireless modules.

Industrial Sensor Interfaces

Low dropout of 0.25V ensures reliable operation even when input voltage is close to output, common in battery-backed industrial systems.
