LM1086-ADJ MDC

Overview

The LM1086-ADJ MDC is a 1.5A low dropout positive regulator from Texas Instruments, housed in a DPAK (TO-263) surface-mount package. It features an adjustable output voltage range of 1.25V to 27.5V, set by two external resistors. The device supports a maximum input voltage of 29V and operates within a junction temperature range of -40°C to 125°C. Typical dropout voltage is 1.3V at full load, with a quiescent current of approximately 5mA. It includes integrated thermal shutdown and current limiting protection circuits for robust operation.

Feature Summary

Adjustable output voltage configuration using two external resistors
Integrated thermal shutdown and current limiting protection
Low dropout performance for efficient power management
Zener-trimmed band gap reference for high accuracy

Applications

Battery-powered systems requiring stable regulation
Post-regulation for switching power supplies
General-purpose linear power supply designs
Portable equipment power management

Procurement Notes

Verify the specific suffix 'MDC' against the official Texas Instruments datasheet to confirm package type and electrical specifications. Ensure compatibility with standard TO-263 footprints if used as a replacement. Confirm RoHS compliance status through manufacturer documentation prior to procurement.

Selection Notes

Select this component when a 1.5A adjustable LDO is required in a surface-mount form factor. Consider the thermal resistance characteristics of the DPAK package for heat dissipation requirements. Verify that the input voltage does not exceed the maximum rating of 29V under all operating conditions.

Part Context

The LM1086 series provides a cost-effective solution for medium-current linear regulation applications. The adjustable variant allows flexible voltage setting, making it suitable for diverse system architectures. It serves as a direct pin-compatible alternative to legacy regulators like the LM317 in modern surface-mount designs.
