MIC5159-1.8BM6

Overview

The MIC5159-1.8BM6 is a linear regulator controller manufactured by Microchip Technology, formerly Micrel Inc. It is designed for positive, adjustable output configurations with a single output channel. The device operates within an input voltage range of 1.65V to 5.5V and draws a supply current of 10mA. It is housed in a SOT-23-6 surface-mount package and supports operation across a temperature range of -40°C to 125°C.

Feature Summary

• Supports positive, adjustable output voltage regulation
• Integrated control circuitry for external pass elements
• Operates with low supply current consumption

Applications

• Battery-powered portable electronics
• Embedded systems requiring efficient power management
• Industrial control modules

Procurement Notes

Verify the manufacturer designation as Microchip Technology, noting the historical Micrel acquisition. Confirm the specific suffix '1.8' indicates the internal reference or fixed setting configuration rather than a variable parameter. Ensure the SOT-23-6 package matches the design footprint requirements.

Selection Notes

Select this component when a compact, single-output linear regulator solution is required with an input voltage up to 5.5V. The SOT-23-6 package offers space efficiency for dense PCB layouts. Consider the 10mA supply current for total system power budget calculations.

Part Context

This part belongs to the MIC5159 series of Super LDO regulators. The series includes variants with different packages and output settings. The MIC5159YM6-TR shares the same core functionality but may differ in packaging or specific electrical tolerances as defined by the manufacturer's datasheet.
