Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for AS7812AT-E1

AS7812AT-E1

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

The AS7812AT-E1 is a three-terminal positive linear voltage regulator from the AS78XXA series by Diodes Incorporated. It provides a fixed output voltage of 12V with an accuracy of ±4% over the full temperature range. The device supports up to 1A output current and operates within an input voltage range of 14.8V to 32V. It features internal short-circuit current limiting, thermal overload protection, and safe-area compensation. The component is housed in a TO-220-3 package and is designed for applications requiring local on-card regulation.

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

Verify that the specific part number matches the required lead-free specification, as the AS7812AT-E1 variant is designated as Lead-Free rather than Green (Halogen/Antimony free). Confirm the package type corresponds to the TO-220-3 configuration. Ensure compatibility with the recommended operating conditions, specifically the maximum input voltage limit of 32V and the junction temperature range of -40°C to +125°C. Check RoHS compliance status against project requirements.

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

Select this regulator when a fixed 12V output is required with up to 1A current capability. Consider the thermal resistance characteristics of the TO-220-3 package for heat dissipation needs. Evaluate the dropout voltage requirements relative to the minimum input voltage of 14.8V. Compare line and load regulation specifications against circuit sensitivity requirements. Verify that the internal protections align with the system's fault tolerance strategy.
