Overview
The LD29300P2M25 is a fixed-output low-dropout voltage regulator from the STMicroelectronics LD29300 series, providing a nominal output of 2.5 V with ±1% tolerance at 25°C. It supports an internal current limit up to 3 A and operates within an input voltage range of 2.5 V to 30 V. The device features a typical dropout voltage of 0.4 V at full load and includes logic-controlled electronic shutdown functionality. It is housed in a P2PAK surface-mount package and maintains operation across a junction temperature range of -40°C to 125°C.
Feature Summary
- Guarantees high accuracy with a fixed output voltage tolerance of ±1% at 25°C
- Features very low dropout voltage characteristics for efficient power management under heavy loads
- Includes internal thermal limiting and current protection mechanisms for enhanced reliability
- Supports logic-controlled electronic shutdown for system power management
Applications
- Power supply switching post regulation
- Series power supply for monitors
- Computer systems
- Battery-powered systems
Procurement Notes
Verify that the specific part number matches the required fixed 2.5 V output configuration and P2PAK package type. Confirm the presence of the inhibit function if logic-controlled shutdown is required for the design. Ensure compatibility with the specified operating temperature range and input voltage limits during integration.
Selection Notes
Select this component when a stable 2.5 V rail is needed for high-current applications requiring minimal voltage drop. Consider the P2PAK package for its thermal dissipation capabilities in surface-mount designs. Evaluate the quiescent current requirements against the specified ranges to ensure efficiency meets system constraints.
Part Context
This regulator belongs to the LD29300 series of 3 A very low drop voltage regulators. The series offers various fixed output voltages and adjustable versions across multiple packages including TO-220, D2PAK, and P2PAK variants. The LD29300P2M25 specifically utilizes the P2PAK form factor for compact surface-mount implementations.
Replacement Considerations
Compatible substitutes within the same family include LD29300P2T25 (TO-220 equivalent) and LD29300D2M25 (D2PAK equivalent). Verify pinout compatibility and thermal resistance differences when transitioning between package types.
