MIC5156-5.0BM

Overview

The MIC5156-5.0BM is a Super LDO Regulator Controller manufactured by Microchip Technology, designed for high-current low-dropout linear voltage regulation. It operates with an input voltage range of 3 V to 36 V and provides a fixed output voltage of 5.0 V. The device features a single regulated output and utilizes an external N-channel power MOSFET as the pass element. It is available in an 8-SOIC surface-mount package and supports operation within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates control circuitry for external N-channel power MOSFETs to achieve low dropout performance
• Provides a fixed 5.0 V regulated output from a wide input voltage range
• Supports high-current regulation applications through external pass element configuration

Applications

• High-current low-dropout linear voltage regulation systems
• Power management circuits requiring external MOSFET drive
• Industrial equipment operating within specified temperature ranges

Procurement Notes

Verify the specific suffix BM against official datasheets to confirm package type and manufacturing origin. Ensure compatibility with external N-channel MOSFET selection for optimal dropout performance. Confirm RoHS compliance status and moisture sensitivity level prior to assembly planning.

Selection Notes

Select this component when a fixed 5.0 V output is required with high current capability via external pass elements. Compare against adjustable variants like MIC5156YM if programmable output is needed. Verify that the 8-SOIC package fits the PCB layout constraints and thermal requirements.

Part Context

Part of the MIC5156/5157/5158 Super LDO Regulator Controller family. These controllers are designed to work with external power MOSFETs rather than integrating the pass transistor internally, allowing for flexible high-current solutions.

Replacement Considerations

MIC5156YM serves as the adjustable equivalent within the same series. For higher current capabilities, consider the MIC5157 or MIC5158 models which share similar controller architectures.
