L7809ACD2T-TR

Low Dropout Ldo Overview

The L7809ACD2T-TR is a positive linear voltage regulator from the STMicroelectronics L78 series, providing a fixed 9 V output with a maximum load current of 1.5 A. It operates within an input voltage range of 10 V to 35 V and features internal thermal overload and short-circuit protection. The device is housed in a D2PAK surface-mount package and supports operation at temperatures up to +125 °C.

Low Dropout Ldo Feature Summary

• Fixed 9 V output regulation for stable power supply applications
• Integrated thermal overload and short-circuit protection mechanisms
• Surface-mount D2PAK packaging for automated assembly

Low Dropout Ldo Applications

• General-purpose positive power supplies
• Local on-card regulation
• Embedded system power management

Low Dropout Ldo Procurement Notes

Verify the specific suffix 'CD2T' against the manufacturer's official datasheet to confirm the D2PAK-3 package type and tape-and-reel orientation. Ensure the AC grade temperature rating aligns with your operational requirements before finalizing procurement orders.

Low Dropout Ldo Selection Notes

Select this component when a fixed 9 V output is required with up to 1.5 A capacity in a surface-mount form factor. Consider the minimum dropout voltage relative to your input source and ensure adequate PCB copper area for heat dissipation given the 1.5 A current capability.

Low Dropout Ldo Part Context

This part belongs to the L78xx family of three-terminal positive regulators, widely used for their simplicity and reliability. The L7809 variant specifically targets 9 V applications, while the D2T suffix indicates the D2PAK surface-mount package configuration offered by STMicroelectronics.

Low Dropout Ldo Replacement Considerations

Cross-reference with other manufacturers offering L7809 equivalents in D2PAK packages. Verify pinout compatibility and thermal performance characteristics to ensure direct substitution without circuit redesign.
