Overview
The LD29300V25 is a fixed-output low-dropout voltage regulator providing a nominal 2.5 V output with ±1% tolerance at 25°C. It supports a guaranteed continuous output current of up to 3 A and features a typical dropout voltage of 0.4 V at full load. The device includes logic-controlled electronic shutdown, internal current limiting, and thermal protection. It operates within an input voltage range of 3.5 V to 8 V and maintains functionality across a junction temperature range of -40°C to +125°C.
Feature Summary
- Fixed 2.5 V output with high accuracy
- Logic-controlled electronic shutdown capability
- Internal short-circuit and thermal protection
Applications
- Power supply switching post regulation
- Series power supply for monitors
- Computer systems
- Battery-powered systems
Procurement Notes
Verify the specific package variant (TO-220, D2PAK, or P2PAK) required for your design, as the base model number corresponds to multiple physical packages. Confirm that the ordering suffix matches the desired enclosure type and tape-and-reel availability if applicable. Ensure the selected component meets the absolute maximum ratings for input voltage and power dissipation under your specific thermal conditions.
Selection Notes
Select this regulator when a stable 2.5 V rail is needed for loads drawing up to 3 A. Consider the thermal resistance values for the chosen package to ensure adequate heat dissipation. Verify that the input voltage remains sufficiently above the output voltage to maintain regulation, accounting for the specified dropout characteristics under varying load and temperature conditions.
Part Context
This component belongs to the LD29300 series of very low drop voltage regulators manufactured by STMicroelectronics. The series offers various fixed output voltages and adjustable versions in multiple surface-mount and through-hole packages. It is designed for applications requiring high current capability with minimal voltage loss between input and output terminals.
Replacement Considerations
Compatible substitutes include other LD29300 series variants such as LD29300D2M25 or LD29300P2M25, which share identical electrical specifications but differ in physical package style.
