E-L6932D1.2

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

The E-L6932D1.2 is an Ultra Low Drop Output (ULDO) linear regulator manufactured by STMicroelectronics, designed for high-performance power management applications. It operates within a supply voltage range of 2V to 14V and supports a continuous output current of up to 2A. The device features an adjustable output voltage configuration ranging from 1.2V to 5V, achieved through external resistor programming. Key electrical characteristics include a maximum drain-source on-resistance (Rdson) of 200mΩ, a quiescent current of 200µA at any load, and a voltage regulation accuracy of 1%. The component incorporates internal short circuit protection and thermal shutdown mechanisms to ensure reliable operation under fault conditions.

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

Verify the specific ordering suffix required for your manufacturing process, as the base part number L6932D1.2 is available in both tube and tape-and-reel configurations. Confirm package availability and lead times directly with authorized distributors or the manufacturer, as stock levels fluctuate. Ensure compliance with RoHS directives and check for any end-of-life notifications before finalizing procurement plans.

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

Select this component when designing circuits requiring a high-current adjustable linear regulator with low dropout characteristics. Consider the thermal resistance of the SO-8 package and the expected ambient temperature to ensure the junction temperature remains within safe limits during continuous operation. Evaluate the need for external compensation capacitors if using very low ESR ceramic output capacitors to maintain loop stability.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

The E-L6932D1.2 belongs to the L6932 family of high-performance 2A ULDO linear regulators from STMicroelectronics. This family includes fixed voltage variants such as 1.5V, 1.8V, and 2.5V, alongside the adjustable D1.2 version. All variants share the same core architecture, featuring an internal 50mΩ N-channel MOSFET and identical pinout configurations, differing primarily in their factory-set or programmable output voltage ranges.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct functional substitutes within the same family include the L6932D1.5, L6932D1.8, and L6932D2.5 for fixed voltage requirements. For adjustable outputs, other L6932 variants can be used if the voltage range meets design needs. Verify pin compatibility and thermal performance when cross-referencing with similar ULDO regulators from other manufacturers.
