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

Select this component when designing portable electronics requiring high efficiency and low heat dissipation. The adjustable output range accommodates various logic levels. Consider the thermal impedance characteristics for pulse loads versus continuous DC operation. Ensure adequate input and output capacitance values are chosen to maintain loop stability, particularly when using low ESR ceramic capacitors.

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

This part belongs to the L6932 family of 2A ULDO linear regulators from STMicroelectronics. The family includes fixed voltage variants (1.5V, 1.8V, 2.5V) and the adjustable D1.2 version. All variants share the same SO-8 package and core electrical characteristics, differing primarily in their output voltage configuration and external resistor requirements for the adjustable model.

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

Direct substitutes within the same family include L6932D1.5TR, L6932D1.8TR, and L6932D2.5TR if fixed voltages are acceptable. For non-ST equivalents, verify pinout compatibility, current handling capabilities, and dropout voltage specifications carefully.
