MIC5504-3.0YMT-TR

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

The MIC5504-3.0YMT-TR is a single-output low-dropout linear regulator manufactured by Microchip Technology, featuring a fixed 3.0V output voltage and a guaranteed 300mA maximum output current. It operates within an input voltage range of 2.5V to 5.5V and maintains high accuracy with ±2% initial tolerance. The device incorporates an internal enable pull-down resistor and an auto-discharge circuit for efficient power management. It utilizes a 4-lead 1.0mm x 1.0mm Thin DFN package and supports an operating junction temperature range from -40°C to +125°C.

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

• Includes an internal pull-down resistor on the enable pin to ensure the output disables when the control signal is floating.
• Features an auto-discharge circuit that activates when the enable pin is low to rapidly discharge external capacitors.
• Provides thermal-shutdown and linear current-limit protection against fault conditions.

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

Verify the specific suffix 'TR' indicates a reel quantity of 5,000 units for the TDFN package as defined in the product identification system. Confirm the 'Y' suffix corresponds to the -40°C to +125°C temperature range and RoHS compliance. Ensure the ordering documentation matches the exact part number MIC5504-3.0YMT-TR to avoid confusion with other package or voltage variants.

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

Select this component for applications requiring a fixed 3.0V rail with up to 300mA load capability in a compact footprint. The internal enable pull-down makes it suitable for systems where the control signal may be tri-stated during processor boot-up. Verify that the application does not require RF transmitter performance, as the datasheet explicitly states the device is unsuitable for such systems.

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

This part belongs to the MIC550x family of general-purpose LDOs designed for portable devices. The MIC5504 variant specifically combines both auto-discharge functionality and an internal enable pull-down resistor, distinguishing it from the MIC5501 (general purpose), MIC5502 (auto-discharge only), and MIC5503 (pull-down only) models within the same series.

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

What happens to the output voltage when the enable pin is left floating?

The MIC5504 includes an internal pull-down resistor on the enable pin, which ensures the output is disabled if the control signal is left floating.

Is the MIC5504-3.0YMT-TR suitable for RF transmitter systems?

No, the datasheet explicitly states that the MIC5501/2/3/4 regulators are not suitable for RF transmitter systems.
