Overview
The LD29150PT80R is a positive fixed-output linear voltage regulator from STMicroelectronics, delivering up to 1.5 A with an 8.0 V output. It features a typical dropout voltage of 400 mV at full load and a maximum of 700 mV. The device includes internal current limiting and thermal shutdown for protection. It operates within a temperature range of -40 °C to +125 °C and exhibits a line regulation of 0.5% and load regulation of 1%. Input bias current is specified at 15 mA.
Feature Summary
- Very low dropout voltage capability for efficient power management
- Guaranteed high output current of 1.5 A
- Integrated internal current limit and thermal shutdown protection
Applications
- Power supply switching post-regulation
- Series power supplies for monitors and TVs
- Battery-powered systems requiring low dropout
Procurement Notes
Verify the specific suffix PT80R confirms the fixed 8.0 V output voltage and PPAK package type. Ensure compatibility with the required operating temperature range and confirm RoHS compliance status for the specific manufacturing batch before integration into final designs.
Selection Notes
Select this component when a stable 8.0 V rail is required with high current capacity. The low dropout characteristic makes it suitable for applications where input voltage is close to the output level. Verify that the thermal dissipation requirements are met given the 1.5 A current rating and package thermal resistance.
Part Context
This part belongs to the LD29150 series of very low drop voltage regulators. The series offers both fixed and adjustable output options. The PT80R variant specifically denotes the fixed 8.0 V version housed in a PPAK surface-mount package, distinguishing it from other voltage variants or through-hole packages in the same family.
Replacement Considerations
Direct substitutes include other LD29150 variants with matching 8.0 V output and PPAK packaging. Cross-referencing pinouts and thermal characteristics is essential when considering alternative manufacturers' equivalents to ensure functional parity.
