MIC5318YMT-TR

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

The MIC5318YMT-TR is a single-output ultra low drop-out (ULDO) regulator from Microchip Technology, housed in a 6-pin 1.6mm x 1.6mm Thin MLF package. It provides a guaranteed 300mA output current with an input voltage range of 2.3V to 6.0V. The device features high accuracy, offering ±2% initial and ±3% over-temperature output voltage variation. Key electrical characteristics include an ultra-low dropout voltage of 110mV at 300mA, low quiescent current of 85µA, and high power supply rejection ratio exceeding 70dB at 1kHz. It operates within a junction temperature range of –40°C to +125°C.

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

Verify the specific output voltage configuration required, as the base part number MIC5318YMT-TR corresponds to the adjustable variant. Confirm that the 6-pin Thin MLF package aligns with your PCB footprint requirements. Ensure compatibility with the operating temperature range of –40°C to +125°C for your intended environment. Cross-reference the datasheet for absolute maximum ratings to prevent damage during installation.

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

Select this component for designs requiring minimal board space due to its compact 1.6mm x 1.6mm footprint. It is ideal for noise-sensitive circuits given its low output noise and high PSRR. Consider the adjustable output feature if precise voltage tailoring is needed using external resistors. Ensure adequate thermal management is planned, as the junction-to-ambient thermal resistance is 100°C/W in the specified package.

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

This component belongs to the MIC5318 series of high-performance ULDO regulators. It is manufactured by Microchip Technology, which acquired Micrel, the original developer. The series includes fixed and adjustable variants available in both Thin MLF and Thin SOT23-5 packages. The 'Y' suffix indicates lead-free and RoHS compliance, while 'MT' denotes the 6-pin Thin MLF package type.
