MIC5319-5.0YML-TR

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The MIC5319-5.0YML-TR is a fixed-output positive linear regulator manufactured by Microchip Technology, delivering a stable 5.0V output with a maximum continuous current of 500mA. It features an input voltage range up to 5.5V and maintains a low dropout voltage of 0.4V at full load. The device incorporates 150µA quiescent current and offers high power supply rejection ratio (PSRR) ranging from 70dB to 60dB across 1kHz to 10kHz frequencies. Integrated protections include overcurrent limiting and thermal shutdown, ensuring reliable operation within a -40°C to 125°C junction temperature range in a compact 6-TMLF package.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Ultra-low dropout voltage design enables efficient regulation with minimal voltage difference between input and output.
• High power supply rejection ratio effectively suppresses noise and ripple from the power source.
• Integrated thermal shutdown and overcurrent protection safeguard the component under fault conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Applications

• Portable electronic devices requiring stable 5V logic levels
• Battery-powered systems with limited headroom
• Noise-sensitive circuitry in consumer electronics

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix YML-TR corresponds to the 6-TMLF tape-and-reel packaging configuration. Confirm that the fixed 5.0V output variant matches the system requirement, as the MIC5319 series offers multiple voltage options. Ensure compatibility with RoHS3 standards and check for any recent product change notices regarding manufacturing sites or material composition updates.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 5.0V rail is required with moderate current demands up to 500mA. Consider the 0.4V dropout specification against the minimum available input voltage to ensure regulation stability. Evaluate the 6-TMLF package dimensions for board space constraints compared to larger SOT packages. Verify that the 150µA quiescent current aligns with battery life requirements for portable applications.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the MIC5319 family of µCap ultra-low dropout regulators designed for small form factor applications. Unlike the dual-channel MIC5330 or lower-current MIC5231 variants, this single-channel device focuses on higher current capability within a tiny footprint. It serves as a direct replacement for older Micrel-branded parts following the acquisition, maintaining pinout and electrical compatibility.
