MIC5156-5.0BN

Overview

The MIC5156-5.0BN is a Super LDO Regulator Controller manufactured by Microchip Technology, designed for positive linear regulator applications. It operates within 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 is housed in an 8-pin DIP package suitable for through-hole mounting. It supports an adjustable output configuration variant with a range of 1.3 V to 36 V. The component functions within an industrial temperature range from -40 °C to +85 °C.

Feature Summary

• Super LDO architecture for high-performance linear regulation
• Wide input voltage capability supporting diverse power sources
• Fixed or adjustable output voltage options for flexible design
• Industrial temperature rating for robust environmental operation

Applications

• Positive linear regulator controller circuits
• Power management systems requiring wide input ranges
• Industrial equipment power supplies
• Embedded system voltage regulation

Procurement Notes

Verify the specific suffix 'BN' against official Microchip documentation to confirm the package type and temperature grade. Ensure compatibility with through-hole assembly processes if using the DIP variant. Cross-reference the datasheet for the MIC5156 series to validate electrical characteristics and pinout configurations before integration into final designs.

Selection Notes

Select this component when a wide input voltage range up to 36 V is required for linear regulation. Consider the fixed 5.0 V output for standard logic levels or the adjustable version for custom voltages. Evaluate the through-hole packaging requirement against available board space and assembly capabilities. Confirm that the operating temperature range meets the application's environmental demands.

Part Context

The MIC5156 belongs to the Super LDO Regulator Controller family from Microchip Technology, formerly Micrel. This series includes variants like the MIC5157 and MIC5158, which offer similar control features but may differ in pin counts or packages. The MIC5156 specifically targets applications needing precise voltage control with low dropout characteristics in a compact form factor.

Replacement Considerations

Check for direct substitutes within the MIC5156 series with different suffixes indicating package variations. Verify functional equivalence with other Super LDO controllers from Microchip or alternative manufacturers, ensuring input/output voltage ranges and thermal performance align with the original design requirements.
