LD1585CD2M33R

Overview

The LD1585CD2M33R is a positive fixed linear voltage regulator IC manufactured by STMicroelectronics. It provides a fixed output voltage of 3.3V with a maximum load current capability of 5A. The device features a low dropout characteristic and fast response time, housed in a surface-mount D²Pak (TO-263AA) package with three terminals. It operates within an input voltage range up to 30V and maintains functionality across an operating temperature range of 0°C to 125°C. The quiescent current is specified at 10 mA.

Feature Summary

Provides a stable fixed positive output voltage
Supports high continuous load current delivery
Utilizes a compact surface-mount thermal package

Applications

General purpose power supply regulation
Pre-regulator stages for switching converters
Battery-powered equipment requiring stable voltage rails

Procurement Notes

Verify component status carefully as this specific part number is listed as obsolete and no longer manufactured by the original producer. Confirm availability through authorized distributors or secondary market suppliers who may hold remaining stock. Ensure that any substitute components meet identical electrical specifications and pinout compatibility requirements for seamless integration into existing designs.

Selection Notes

Select this component when a robust 5A linear regulation solution is required for applications tolerant of higher dissipation. Consider thermal management strategies due to the power loss inherent in linear regulation at high currents. Evaluate input-output voltage differentials to ensure operation remains within safe thermal limits for the D²Pak package.

Part Context

This regulator belongs to the LD1585 family of low-dropout positive voltage regulators designed for high-current applications. The series offers both adjustable and fixed output variants, providing flexibility for various power management needs. The LD1585CD2M33R specifically denotes the fixed 3.3V version in the D²Pak package, targeting space-constrained PCB layouts requiring significant current capacity.
