KA7906TU

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

The KA7906TU is a fixed negative linear voltage regulator from the 7906 series, manufactured by Fairchild Semiconductor. It provides a nominal output voltage of -6V with a maximum continuous output current of 1A. The device accepts an input voltage range between -35V and -11V. It is housed in a TO-220-3 package with three pins and operates within a temperature range of 0°C to 125°C.

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

• Fixed negative voltage regulation for stable power supply applications
• Integrated thermal overload protection to prevent damage during fault conditions
• Safe area compensation ensures reliable operation under varying load and temperature conditions

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

• Negative rail generation in dual-supply electronic circuits
• Power conditioning for analog signal processing equipment
• General-purpose DC power supply modules requiring negative voltage rails

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

Verify the manufacturer marking matches Fairchild Semiconductor or ON Semiconductor due to corporate integration. Confirm the package type is TO-220-3 and the suffix TU indicates through-hole mounting. Check RoHS compliance status if required for specific manufacturing standards. Ensure the part number corresponds to the fixed -6V variant rather than adjustable versions.

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

Select this component when a stable -6V negative rail is required with up to 1A load capacity. Ensure the input voltage remains above -11V to maintain regulation. Consider thermal management requirements as the TO-220 package dissipates heat based on the voltage drop across the device. Verify that the operating environment stays within the specified 0°C to 125°C range for optimal performance.

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

This regulator belongs to the widely used 79xx series of negative linear voltage regulators. The KA prefix typically denotes Fairchild Semiconductor production. These devices are standard components for creating negative voltage supplies in conjunction with positive regulators like the 78xx series. The TO-220 package allows for easy mounting on heatsinks for higher power dissipation scenarios.
