Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for KA7805ERTF

KA7805ERTF

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

The KA7805ERTF is a three-terminal positive voltage regulator from the KA78XXE series, manufactured by onsemi. It provides a fixed output voltage of 5 V with a tolerance of ±4% at 25°C and supports an output current up to 1 A. The device operates within an input voltage range of 7 V to 20 V for this specific configuration and features thermal overload protection, short-circuit protection, and output transistor safe operating area protection. It is housed in a D-PAK package and supplied in tape and reel format.

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-to-DC conversion circuits
Local regulation for card distribution systems
Power supplies requiring fixed positive voltage outputs

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

Verify the exact part number KA7805ERTF against official onsemi documentation to confirm the D-PAK package and tape and reel parking method. Ensure compatibility with system requirements regarding the -40°C to +125°C operating temperature range and absolute maximum ratings before procurement.

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

Select this component when a fixed 5 V output with 1 A capability is required in a surface-mount D-PAK package. Consider the ±4% output voltage tolerance and the need for external capacitors (0.33 μF input, 0.1 μF output) for stability. Verify that the application does not exceed the 35 V maximum input voltage limit.

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

This device belongs to the KA78XXE series of three-terminal positive regulators originally developed by Fairchild Semiconductor and now managed by onsemi following integration. The series offers various fixed output voltages including 5, 6, 8, 9, 10, 12, 15, 18, and 24 V options across TO-220 and D-PAK packages.
