MIC5319-3.3YML-TR

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

The MIC5319-3.3YML-TR is a fixed-output linear regulator from Microchip Technology, providing a stable 3.3V output with a maximum current capacity of 500mA. It operates within an input voltage range up to 5.5V and features a typical dropout voltage of 0.4V at full load. The device incorporates internal protection mechanisms including overcurrent limiting and thermal shutdown. It is housed in a compact 6-TMLF (2x2 mm) surface-mount package, suitable for space-constrained designs requiring efficient power management.

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

Verify the specific suffix YML indicates the 6-TMLF package variant. Confirm the trailing TR denotes tape-and-reel packaging format. Ensure compatibility with RoHS3 standards if required by target market regulations. Cross-reference the manufacturer part number with official Microchip documentation to validate revision levels before integration into production schedules.

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

Select this component when a fixed 3.3V rail is required with moderate current demands up to 500mA. It is appropriate for applications prioritizing low dropout performance and high PSRR over ultra-low quiescent current. Compare against MIC5319 variants with different output voltages or packages if system constraints differ. Evaluate thermal dissipation requirements based on the expected input-to-output voltage differential and load current.
