MIC5156-5.0YM

Voltage Regulators - Linear Regulator Controllers Overview

The MIC5156-5.0YM is a Super LDO Regulator Controller manufactured by Microchip Technology, housed in an 8-pin SOIC package. It provides a fixed 5.0V output with a supply voltage range of 3V to 36V and operates within a temperature range of -40°C to +85°C. The device features a typical operating current of 4.5mA and a shutdown current below 1µA. It includes an internal gate-to-source protective clamp and supports optional constant-current limiting via an external sense resistor.

Voltage Regulators - Linear Regulator Controllers Procurement Notes

Verify the specific ordering suffix 'YM' corresponds to the 8-pin SOIC package and industrial temperature range (-40°C to +85°C). Confirm that the component is sourced from authorized distributors to ensure authenticity. Check for RoHS compliance status as indicated in official documentation before procurement.

Voltage Regulators - Linear Regulator Controllers Selection Notes

Select this controller when a fixed 5.0V output is required without external programming resistors. Ensure the design accommodates an external N-channel MOSFET for the pass element. Verify that the application requires an external gate drive supply, as this variant lacks an internal charge pump unlike the MIC5157/8 family members.

Voltage Regulators - Linear Regulator Controllers Part Context

This component belongs to the MIC5156/5157/5158 Super LDO Regulator Controller family. While the MIC5157 and MIC5158 feature internal charge pumps for gate drive, the MIC5156 requires an external gate drive supply voltage (VP) to operate the external power MOSFET. This distinction defines its placement within the product line.

Voltage Regulators - Linear Regulator Controllers FAQ

Does the MIC5156-5.0YM include an internal charge pump?

No, the MIC5156 requires an external gate drive supply voltage (VP) to drive the external MOSFET gate.

How is current limiting implemented on this controller?

Current limiting is implemented by placing an external sense resistor between VDD and the Drain pin; the controller limits current when the voltage drop across the resistor reaches approximately 35mV.
