Overview
The LD29300P2M18 is a fixed-output linear voltage regulator from the STMicroelectronics LD29300 series, housed in a P2PAK package. It provides a nominal output voltage of 1.8V with a guaranteed maximum output current of 3A. The device features a typical dropout voltage of 0.4V at full load and maintains high accuracy with ±1% tolerance at 25°C. It includes internal current limiting and thermal shutdown protection, along with logic-controlled electronic shutdown functionality.
Feature Summary
- Guarantees up to 3A output current capability for high-load applications
- Features very low dropout voltage characteristics for efficient power management
- Includes internal current limit and thermal limit protections
- Supports logic-controlled electronic shutdown via an inhibit pin
Applications
- Power supply switching post regulation
- Series power supply for monitors
- Series power supply for VCRs and TVs
- Computer systems
- Battery-powered systems
Procurement Notes
Verify the specific package type and suffix against official datasheets before procurement. Confirm that the component meets all required electrical specifications for the target application. Check for any obsolescence notices or alternative part recommendations from the manufacturer. Ensure compliance with relevant environmental standards such as RoHS if applicable to the design requirements.
Selection Notes
Select this regulator when a stable 1.8V rail is needed with high current capacity. Consider the P2PAK package for its thermal performance in surface-mount designs. Evaluate the input voltage range to ensure it stays within the 30V absolute maximum rating. Verify that the system can accommodate the quiescent current requirements during both active and shutdown modes.
Part Context
This component belongs to the LD29300 series of very low dropout voltage regulators. The series offers various fixed output voltages and adjustable versions across multiple packages including TO-220, D2PAK, and P2PAK. The LD29300P2M18 specifically utilizes the P2PAK housing for the 1.8V fixed output variant.
Replacement Considerations
Consult the official LD29300 datasheet order codes table for direct equivalents. Other variants in the series may share similar electrical characteristics but differ in output voltage or package style.
