LT3085MPMS8E#PBF

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

The LT3085MPMS8E#PBF is a precision adjustable low dropout linear regulator manufactured by Analog Devices Inc. It provides a maximum output current of 500mA and supports an output voltage range from 0V to 36V. The device operates with an input voltage between 1.2V and 36V, featuring a typical dropout voltage of 275mV at full load. It utilizes a single external resistor for voltage programming via a 10µA reference current. The component is housed in an 8-lead MSOP package with an exposed pad and is rated for an operating temperature range of -55°C to +125°C.

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

Verify the MP grade designation confirms the extended -55°C to +125°C industrial temperature range required for your application environment. Ensure the 8-lead MSOP package footprint matches your PCB layout constraints. Confirm RoHS compliance status if environmental regulations apply to your manufacturing process. Cross-reference the datasheet revision to ensure compatibility with your design specifications.

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

Select this component when precise voltage adjustment down to zero is necessary without complex feedback networks. Consider the exposed pad requirement for thermal management and electrical connection to the output node. Evaluate the need for separate control voltage inputs if minimizing dropout voltage below standard LDO limits is critical for system efficiency.

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

This part belongs to the LT3085 family of precision linear regulators designed for high performance applications. The MP suffix indicates a military-grade or extended temperature variant compared to standard commercial grades. It shares architectural similarities with other Analog Devices LDOs but distinguishes itself through its unique current-source-based regulation method.
