KA7808ERTM

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

The KA7808ERTM is a three-terminal positive linear voltage regulator from the KA78XXE series, manufactured by onsemi. It provides a fixed output voltage of 8 V with a maximum output current of 1 A. The device operates within an input voltage range of 10.5 V to 23 V and supports junction temperatures from -40°C to +125°C. Key electrical characteristics include a line regulation of up to 160 mV and load regulation of up to 160 mV. It features internal thermal overload protection, short-circuit protection, and safe operating area (SOA) protection. The component is housed in a D-PAK (TO-252) surface-mount package.

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

Integrated thermal overload protection for temperature safety
Built-in short-circuit protection for fault tolerance
Output transistor safe operating area protection

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

DC-to-DC conversion circuits
Local voltage regulation for biasing applications
Power supply sections requiring fixed positive voltage rails

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

Verify the manufacturer origin as Fairchild Semiconductor legacy parts are now managed under onsemi. Confirm that the ordering suffix 'ERTM' corresponds to the D-PAK tape and reel packaging method. Ensure compliance with RoHS standards and check for any specific REACH-SVHC requirements relevant to your region before finalizing procurement.

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

Select this component when a fixed 8 V output is required with up to 1 A load capability in a surface-mount format. Consider the minimum input voltage requirement of 10.5 V to ensure sufficient headroom. Evaluate thermal management needs, as the device relies on adequate heat sinking to deliver full current capacity without triggering thermal shutdown.

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

This part belongs to the KA78XXE series of three-terminal positive regulators. It shares functional similarities with other members like the KA7805ERTM and KA7809ERTM but differs in its fixed output voltage specification. The series is designed for general-purpose power management tasks where reliability and basic protection features are prioritized over high-frequency performance.
