MIC5236-3.0YM

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

The MIC5236-3.0YM is a low quiescent current, µCap LDO regulator manufactured by Microchip Technology (originally Micrel). It provides a fixed 3.0V output with a maximum continuous current of 150mA in an 8-pin SOIC package. The device operates within a wide input voltage range of 2.3V to 30V and features ultra-low ground current of 20µA at 100µA load. Key electrical parameters include a dropout voltage of 300mV at full load, ±1.0% initial output accuracy, and stability with ceramic or tantalum capacitors as small as 1.0µF.

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

Verify the specific suffix 'YM' corresponds to the 8-pin SOIC package variant when sourcing. Confirm that the component is sourced from authorized distributors to ensure authenticity, as the datasheet indicates historical manufacturing by Micrel prior to acquisition. Check RoHS compliance status if required for your assembly process.

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

Select this part for designs requiring high input voltage tolerance and low standby current. Ensure the application utilizes a minimum 1.0µF ceramic or tantalum output capacitor to maintain loop stability. Consider thermal dissipation requirements based on the difference between input and output voltages at the expected load current.

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

This component belongs to the MIC5236 family of low-dropout regulators designed for high-input voltage applications. It shares architectural similarities with the MIC2950 but offers reduced quiescent current and smaller packaging options. The family includes adjustable and fixed voltage variants available in both SOIC-8 and MSOP-8 packages.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

MIC5236-3.0BMM is the MSOP-8 package equivalent. MIC5236-3.0YMM is the MSOP-8 Pb-Free variant. Direct pin-to-pin replacements may require verification of thermal resistance differences between SOIC and MSOP packages.
