Overview
The LD29150V80 is a fixed-output low-dropout voltage regulator from STMicroelectronics, providing a stable 8 V output with a maximum current capacity of 1.5 A. It features a typical dropout voltage of 400 mV at full load and very low ground current consumption. The device operates with an input voltage range up to 14 V and includes internal protections against overcurrent and thermal overload. Designed for high-accuracy applications, it maintains output voltage tolerance within ±1% at 25 °C.
Feature Summary
- Very low dropout voltage enabling efficient operation in battery-powered systems
- Guaranteed 1.5 A output current capability for high-load applications
- Internal current limiting and thermal shutdown protection mechanisms
- High accuracy fixed output voltage regulation
Applications
- Power supply switching post-regulation
- Series power supplies for monitors and TVs
- Battery-powered electronic systems
- Computer system power distribution
Procurement Notes
Verify the specific suffix 'V80' confirms the 8 V fixed output variant when ordering. Ensure the TO-220-3 package matches your thermal and mechanical design requirements. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the datasheet revision date to ensure compatibility with latest application notes.
Selection Notes
Select this component when a fixed 8 V rail is required with high current drive capabilities. The low dropout characteristic makes it suitable for inputs close to the output voltage. Consider the TO-220 package for through-hole mounting and adequate heat dissipation without additional heatsinks under moderate loads.
Part Context
The LD29150 series comprises high-current, low-dropout regulators available in various fixed and adjustable output voltages. The LD29150V80 specifically denotes the 8 V fixed version. The series is designed for applications requiring high efficiency and stability, offering robust protection features integrated into a compact semiconductor solution.
Replacement Considerations
Check for direct pin-compatible alternatives with identical 8 V output and 1.5 A rating. Verify that substitute components maintain similar dropout voltage characteristics and thermal protection thresholds to ensure circuit performance parity.
