Overview
The LD29080PT50R is a fixed-output low-dropout linear voltage regulator manufactured by STMicroelectronics, delivering a guaranteed output current of up to 800 mA. It provides a precise 5.0 V output with ±1% accuracy at 25 °C. The device features a typical dropout voltage of 400 mV at full load and operates within an input voltage range from 2.5 V to 13 V. It utilizes a PPAK surface-mount package measuring 6.6 mm x 6.2 mm x 2.4 mm. Internal protections include thermal limiting and current limiting, ensuring reliable operation across a temperature range of -40 °C to +125 °C.
Feature Summary
- Guarantees 800 mA output current capability for medium-current applications
- Features ultra-low dropout voltage characteristics for efficient power management
- Includes internal thermal and current limiting protection mechanisms
Applications
- Post-regulation stages in switching power supplies
- Power supply modules for computer systems
- Battery-powered electronic devices requiring stable voltage rails
Procurement Notes
Verify the specific suffix 'PT50R' against official STMicroelectronics documentation to confirm the 5.0 V fixed output and PPAK packaging configuration. Ensure compatibility with required PCB footprint dimensions and thermal dissipation requirements before finalizing procurement orders.
Selection Notes
Select this component when a stable 5.0 V rail is required with high current capacity. The low dropout characteristic makes it suitable for battery-operated systems where maximizing headroom is critical. Verify that the application does not exceed the maximum input voltage limit of 13 V.
Part Context
This part belongs to the LD29080 series of medium-current, high-accuracy low-dropout regulators. The series offers both fixed and adjustable output options, designed for applications demanding tight voltage regulation and minimal ground current consumption under varying load conditions.
Replacement Considerations
Consult official STMicroelectronics substitution guides for verified alternatives. Generic LDO replacements may lack the specific 800 mA guarantee or exact pinout compatibility.
