Overview
The LD29150DT50 is a fixed-output low-dropout linear voltage regulator manufactured by STMicroelectronics. It provides a stable 5 V output with a maximum current capacity of 1.5 A. The device operates within an input voltage range of 3 V to 14 V and maintains regulation across a junction temperature range of -40 °C to +125 °C. Key electrical specifications include a typical dropout voltage of 400 mV at full load, a line regulation of 0.5 %, and a load regulation of 1 %. The unit is housed in a surface-mount DPAK (TO-252) package.
Feature Summary
- Guarantees high output current capability up to 1.5 A for demanding loads
- Features very low dropout voltage for efficient power management
- Includes internal protection against overcurrent and thermal overload
Applications
- Post-regulation for switching power supplies
- Series power supply for monitors and televisions
- Battery-powered electronic systems
Procurement Notes
Verify the exact suffix designation when ordering, as variations such as 'R' indicate specific tape-and-reel packaging configurations. Confirm that the required output voltage tolerance and thermal performance align with the system design constraints before finalizing procurement.
Selection Notes
Select this component when a fixed 5 V rail is required with high current drive capabilities. Ensure the input voltage remains within the specified limits to maintain the low dropout characteristic. Consider the thermal dissipation requirements of the DPAK package under maximum load conditions.
Part Context
This part belongs to the LD29150 series of high-current, high-accuracy low-dropout regulators. The series offers both fixed and adjustable output options, designed for applications requiring minimal voltage drop and ground current. The DT50 variant specifically denotes the fixed 5 V output configuration.
Replacement Considerations
Compatible substitutes within the same family include LD29150DT33R for 3.3 V output or LD29150DT15R for 1.5 V output, provided the pinout and thermal characteristics remain compatible with the existing footprint.
