Overview
The LD1086V36 is a fixed-output low dropout positive voltage regulator from STMicroelectronics, delivering up to 1.5 A of output current. It features a typical dropout voltage of 1.3 V at full load and supports input voltages ranging from 3.4 V to 30 V. The device provides a stable 3.6 V output with a tolerance of 1% and operates within a temperature range of -40°C to +125°C. Packaged in a TO-220-3 through-hole case, it includes internal current limiting and thermal shutdown protection for robust performance in power management applications.
Feature Summary
- Fixed 3.6 V output voltage with high accuracy
- Capable of supplying continuous 1.5 A output current
- Integrated thermal overload and short-circuit protection
Applications
- Battery-powered systems requiring efficient linear regulation
- Post-regulation stages for switching power supplies
- General-purpose power supply circuits in industrial equipment
Procurement Notes
Verify the specific suffix (e.g., DG) against the manufacturer's official datasheet to confirm package type and pinout compatibility. Ensure that the required output current does not exceed the thermal limits defined by the ambient operating conditions and heatsinking requirements specified in the product documentation.
Selection Notes
Select this component when a fixed 3.6 V rail is required with moderate current demands up to 1.5 A. Consider the dropout voltage characteristics relative to the minimum input voltage available in the design. Evaluate thermal dissipation capabilities based on the TO-220 package and expected power loss under maximum load conditions.
Part Context
This part belongs to the LD1086 series of adjustable and fixed low-dropout positive voltage regulators. The series is designed for applications requiring high efficiency and stability with minimal external components. The LD1086V36 specifically offers a fixed output variant, simplifying circuit design compared to adjustable versions while maintaining the series' reliability and protection features.
