LD29150V25

Overview

The LD29150V25 is a high-current, high-accuracy low-dropout voltage regulator from the LD29150 series by STMicroelectronics. It provides a fixed 2.5 V output with a maximum guaranteed current of 1.5 A. The device features a typical dropout voltage of 400 mV at full load and very low ground current. It includes internal current limiting and thermal shutdown protection. The component operates within an input voltage range up to 30 V and supports junction temperatures up to 125 °C.

Feature Summary

• Guarantees high output current capability for demanding loads
• Features extremely low dropout voltage for efficient power management
• Includes built-in overcurrent and thermal overload protection mechanisms

Applications

• Power supply switching post-regulation
• Series power supplies for monitors and televisions
• Computer systems requiring stable voltage rails
• Battery-powered electronic devices

Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout compatibility and package type. Confirm that the fixed 2.5 V output aligns with circuit requirements. Check for RoHS compliance status in the latest manufacturer documentation before finalizing procurement decisions.

Selection Notes

Select this component when a stable 2.5 V rail is required with high current capacity. Ensure the input voltage does not exceed the maximum rating. Consider the thermal performance if operating near the upper temperature limits or under continuous heavy load conditions.

Part Context
