L6932D2.5

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The L6932D2.5 is a high-performance Ultra Low Drop Output (ULDO) linear regulator manufactured by STMicroelectronics, designed for applications requiring stable power delivery within a compact footprint. It operates with an input voltage range of 2V to 14V and provides a fixed output voltage of 2.5V with a regulation accuracy of 1%. The device supports up to 2A continuous load current and features a maximum drain-source ON resistance (Rdson) of 200mΩ. Key electrical characteristics include a quiescent current of 200µA at any load, a line regulation of 5mV, and a load regulation of 15mV. It incorporates short circuit protection with a current limit of 2.5A and thermal shutdown set at 150°C with 20°C hysteresis.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix 'D' indicates the SO-8 package variant when sourcing. Confirm that the 'TR' suffix denotes tape and reel packaging if required for automated assembly. Ensure compatibility with the 2V to 14V input range and 2.5V fixed output requirement. Check for end-of-life status as some distributors list this component as obsolete or transitioning. Validate thermal management requirements based on the 62°C/W junction-to-ambient resistance for your specific PCB layout.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select the L6932D2.5 when a fixed 2.5V output is needed with high efficiency and low dropout characteristics. Consider the SO-8 (4+4) package for space-constrained designs. Evaluate thermal performance carefully, as the device dissipates significant heat at high currents; use pulse loads or adequate copper area to manage junction temperature. Compare against adjustable versions if variable output is required, noting that the fixed version offers simplified design without external resistors.
