MIC5501-3.0YMT-TZ

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

The MIC5501-3.0YMT-TZ is a single-output low-dropout linear regulator manufactured by Microchip Technology, providing a fixed 3.0V output with a guaranteed maximum current of 300 mA. It operates within an input voltage range of 2.5 V to 5.5 V and features high output accuracy of ±2%. The device exhibits a typical quiescent current of 38 μA and achieves a dropout voltage of 160 mV at full load. Designed for stability with 1 μF ceramic capacitors, it includes thermal shutdown and current limit protection. The component is housed in a 4-lead 1 mm x 1 mm Thin DFN package and supports an operating junction temperature range from –40°C to +125°C.

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

Verify the specific suffix 'TZ' against official Microchip documentation to confirm the 10,000-unit reel packaging configuration. Ensure that the ordering process explicitly references the complete part number MIC5501-3.0YMT-TZ to distinguish it from other tape-and-reel options like T5 or TR. Confirm RoHS compliance status through the manufacturer's current product release notes before finalizing procurement orders.

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

Select this component when a fixed 3.0V rail is required with minimal space constraints due to its 1 mm x 1 mm footprint. It is suitable for designs needing high efficiency under light loads given its low quiescent current profile. Engineers should ensure the application does not require auto-discharge functionality, as the MIC5501 variant lacks this feature compared to MIC5502/4 models. Verify that the system can accommodate the necessary 1 μF input and output capacitance for optimal transient response.

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

This device belongs to the MIC550x family of general-purpose LDO regulators designed for portable electronic systems. The family shares common electrical characteristics but varies in control features; specifically, the MIC5501 model provides basic enable/disable control without internal pull-down resistors or auto-discharge circuits. This distinguishes it from the MIC5503 and MIC5504 variants which offer enhanced enable pin behaviors for processor boot-up scenarios.
