MIC5202-5.0YM-TR

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

The MIC5202-5.0YM-TR is a dual linear voltage regulator from Microchip Technology, housed in an 8-pin SOIC package with a -40°C to +125°C operating temperature range. It provides two independent 5.0V outputs with 1% accuracy and up to 100 mA continuous current per channel. The device features low dropout voltage (typically 210 mV at full load), low ground current (1 mA at 100 mA), and excellent line/load regulation. Key protections include reverse-battery protection, current limit, and thermal shutdown.

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

Verify the specific suffix '-TR' indicates reel packaging of 2,500 units per the product identification system. Confirm the 'Y' designation corresponds to the extended industrial temperature range (-40°C to +125°C). Ensure the 'M' package code matches the required 8-pin SOIC footprint. Cross-reference the datasheet revision history for any recent manufacturing or assembly changes.

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

Select this component for applications requiring two isolated regulated rails from a single IC. The dual enable pins allow independent control of each output. Consider the thermal resistance characteristics if high power dissipation is expected. Verify that the required output capacitor meets stability requirements, typically 1 µF or greater.

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

How does the MIC5202 handle reverse battery connections?

The device includes built-in reverse-battery protection, safeguarding the internal circuitry against incorrect polarity on the VIN inputs.

What is the behavior of the MIC5202 when the enable pin is low?

Forcing the enable pin low disables the regulator and places it in a zero-off mode state, reducing ground pin current to nearly zero.
