AS7805ADTR-E1

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

The AS7805ADTR-E1 is a three-terminal positive voltage regulator from the AS78XXA series by Diodes Incorporated. It provides a fixed output voltage of 5V with an output current capability of up to 1A. The device features internal current limiting, thermal shutdown protection, and safe-area compensation for overload immunity. It operates within an input voltage range of up to 25V and supports junction temperatures from -40°C to +125°C. The component is housed in a TO-252-2 (5) or TO252 (Type CJ) surface-mount package.

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

Verify that the ordering suffix matches the required package type, as the AS7805ADTR-E1 specifically denotes the TO-252-2 (5) or TO252 (Type CJ) configuration. Confirm RoHS compliance status and ensure the marking ID corresponds to the specific manufacturing batch. Check for any automotive qualification requirements if the application demands AEC-Q100 standards or IATF 16949 certified facility production.

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

Select this component when a fixed 5V output at 1A is required in a compact surface-mount form factor. Ensure the input voltage does not exceed the maximum rating of 25V for the 5V variant. Consider thermal resistance values for heat dissipation planning, as power dissipation is internally limited but requires adequate heatsinking for sustained 1A loads. Verify compatibility with PCB pad layouts provided for the specific package option.

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

This part belongs to the AS78XXA series of 1A three-terminal positive voltage regulators. The series includes variants for different output voltages such as 12V and 15V, packaged in TO-220-3, TO-263-2, and TO-252 formats. The 'E1' suffix typically indicates a specific packaging or environmental compliance designation within the manufacturer's lineup, distinct from other suffixes like 'G1'.
