L7806ACD2T

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

The L7806ACD2T is a positive linear voltage regulator from the L78 series, manufactured by STMicroelectronics. It provides a fixed output voltage of 6 V with a maximum output current of 1.5 A. The device operates within an input voltage range up to 35 V and features a typical power supply rejection ratio (PSRR) of 59 dB. It is housed in a D2PAK (TO-263) surface-mount package with three pins. The component supports a junction temperature range from -40 °C to +125 °C and includes internal protection mechanisms such as thermal overload shutdown and safe area protection.

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

Verify the specific suffix 'CD2T' confirms the D2PAK surface-mount package variant rather than the through-hole TO-220 version. Confirm RoHS compliance status for environmental requirements. Check for any specific EOL or PCN notices as availability may vary. Ensure the ordering part number matches the exact thermal and electrical specifications required for the design.

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

Select this component when a fixed 6 V output is required at currents up to 1.5 A in a surface-mount application. Consider the thermal resistance of the D2PAK package and ensure adequate PCB copper area for heat sinking. Verify that the input voltage remains within the 35 V absolute maximum rating under all operating conditions. Compare line and load regulation specs against system tolerance requirements.

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

This part belongs to the L78xx family of three-terminal positive linear regulators. These devices are widely used for local on-card regulation where efficiency is not the primary concern but simplicity and low cost are valued. The L7806ACD2T specifically adapts this topology for surface-mount assembly, offering similar electrical performance to its through-hole counterparts while fitting modern PCB layouts.

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

Compatible substitutes include other manufacturers' 6 V 1.5 A linear regulators in D2PAK packages, such as the LM7806 variants. Ensure pinout compatibility (Input, Ground, Output) before substitution. Verify that replacement parts meet the same thermal and electrical safety margins.
