Overview
The LD29150DT50R is a fixed-output linear voltage regulator from STMicroelectronics, providing a stable 5V output with a maximum current capacity of 1.5A. It operates within an input voltage range of 3V to 14V and features a typical dropout voltage of 400mV at full load, with a maximum specified dropout of 700mV. The device includes internal protections against overcurrent and thermal overload, ensuring reliable operation across a wide temperature range from -40°C to +125°C.
Feature Summary
- Guarantees high output current capability up to 1.5A for demanding loads
- Features very low dropout voltage characteristics for efficient power management
- Includes built-in internal current limiting and thermal shutdown protection
Applications
- Power supply switching post-regulation
- Series power supplies for monitors and televisions
- Computer systems requiring stable logic voltages
- Battery-powered equipment needing extended runtime
Procurement Notes
Verify the specific suffix DT50R confirms the 5V fixed output and DPAK package configuration. Ensure compatibility with surface-mount assembly processes using TO-252 (DPAK) footprints. Confirm RoHS compliance status matches project requirements before finalizing procurement orders.
Selection Notes
Select this component when a fixed 5V rail is required with high current drive capabilities. The low dropout characteristic makes it suitable for applications where input voltage headroom is limited. Internal thermal and current protection simplifies design by reducing external component count compared to unprotected regulators.
Part Context
This part belongs to the LD29150 series of high-current, low-dropout regulators. The series offers both fixed and adjustable output options with high accuracy. The DT50R variant specifically denotes the 5V fixed output version housed in a DPAK surface-mount package, designed for general-purpose power regulation tasks.
Replacement Considerations
Compatible substitutes include other LD29150 variants with different output voltages or packages, such as LD29150DT15R or LD29150DT33R, provided the voltage requirement differs. Cross-referencing pinouts and thermal performance is essential when substituting with similar LDOs from other manufacturers.
