MIC5305YML-TR

MIC5305YML-TR Description

The MIC5305YML-TR from Microchip Technology is a high-performance, low-dropout (LDO) linear voltage regulator designed for precision power management in space-constrained applications. This adjustable positive-output regulator delivers up to 150mA of output current with an ultra-low dropout voltage of 0.85V @ 150mA, making it ideal for battery-powered and portable devices. The input voltage range spans up to 5.5V, while the output is adjustable from 1.25V to 5.5V, providing flexibility for various low-voltage circuits. With a quiescent current of just 150 µA, the MIC5305YML-TR ensures efficient power utilization, extending battery life in energy-sensitive designs.

MIC5305YML-TR Features

• Adjustable Output: Configurable from 1.25V to 5.5V for versatile voltage requirements.
• Low Dropout: Only 0.85V dropout at full load (150mA), maximizing efficiency in low-input-voltage scenarios.
• Ultra-Low Quiescent Current: 150 µA minimizes power waste in standby or idle modes.
• High PSRR: Excellent noise rejection (85dB @ 1kHz, decreasing to 65dB @ 10kHz) ensures clean power for sensitive analog/digital loads.
• Robust Protection: Integrated over-current and over-temperature safeguards enhance reliability.
• Enable Control: External enable pin allows for power sequencing or shutdown to reduce leakage.
• Compact Package: 6-pin DFN (2x2mm) surface-mount package suits space-constrained PCB designs.
• Compliance: ROHS3 and REACH compliant, with MSL1 (unlimited floor life) for easy handling.
