MAX8867EUK32+T

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

The MAX8867EUK32+T is a low-noise, low-dropout linear regulator manufactured by Analog Devices Inc./Maxim Integrated. It operates from an input voltage range of 2.5V to 6.5V and delivers up to 150mA output current. The device provides a fixed preset output voltage of 3.15V with ±1.4% accuracy. Typical dropout voltage is 165mV at 150mA load, and output noise is 30µVRMS. Quiescent supply current is 100µA, reducing to 10nA in shutdown mode. It features thermal-overload protection, short-circuit protection, reverse battery protection, and logic-controlled shutdown.

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

Verify the exact part number suffix against official manufacturer documentation to confirm package type and temperature rating. Confirm RoHS compliance status through authorized distributors or direct manufacturer channels. Ensure sourcing channels are legitimate to avoid counterfeit components. Check for any specific handling requirements related to electrostatic discharge during storage and installation.

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

Select this component for battery-powered applications requiring low quiescent current and stable regulation. The P-channel MOSFET pass transistor maintains constant current draw regardless of load or dropout conditions. Verify that the required output voltage matches the factory-set 3.15V preset. Ensure input voltage remains within the 2.5V to 6.5V operating range for proper functionality.

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

This device belongs to the MAX8867/MAX8868 family of low-noise, low-dropout linear regulators. The MAX8867 and MAX8868 are pin-compatible except for the BP pin functionality. The MAX8868 variant includes an auto-discharge function not present in the MAX8867. Both devices utilize a regular or thin 5-pin SOT23 package and are designed primarily for portable electronic systems.

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

The MAX8867EUK32+T is pin-compatible with the MAX8863 and MAX8864 series, excluding the BP pin configuration. Designers may consider these alternatives if specific bypass pin requirements differ. Verify electrical characteristics and package dimensions before substitution.
