Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for KA7812ETSTU

KA7812ETSTU

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

The KA7812ETSTU is a three-terminal positive voltage regulator from the KA78XXE series, manufactured by ON Semiconductor. It provides a fixed output voltage of 12 V with an output current capability up to 1 A. The device operates within a junction temperature range of -40°C to +125°C and utilizes a D-PAK surface-mount package. Electrical characteristics include thermal overload protection, short-circuit protection, and output transistor safe operating area protection.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

Integrated thermal overload protection prevents damage during overheating conditions.
Built-in short-circuit protection safeguards the device against output faults.
Output transistor safe operating area protection ensures reliability under varying load conditions.

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

DC power supply regulation
Local on-card regulation for distribution networks
Elimination of single-point air conditioning in embedded systems

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

Verify the specific ordering suffix 'ST' against the official ON Semiconductor datasheet or website, as standard documentation lists 'TM' and 'TF' for tape and reel packaging. Confirm that the component matches the KA7812ETM or KA7812ETF variants regarding pinout and electrical specifications before procurement.

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

Select this component when a fixed 12 V output is required with up to 1 A current capacity in a surface-mount form factor. Ensure adequate heat sinking is provided if the input-output differential voltage results in power dissipation exceeding the thermal resistance limits of the D-PAK package.

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

This part belongs to the KA78XXE family of three-terminal positive regulators originally developed by Fairchild Semiconductor and now managed by ON Semiconductor following their integration. The series offers multiple fixed output voltages and is designed for wide-ranging applications requiring reliable linear regulation.

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

Direct replacements include KA7812ETM (Tape & Reel) and KA7812ETF (Tape & Reel). Verify compatibility with KA7812ETU if transitioning from through-hole to surface-mount assembly.
