KA337TU

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

The KA337TU is a three-terminal negative adjustable voltage regulator manufactured by onsemi. It provides an output current exceeding 1.5 A with an adjustable output voltage range from -1.25 V to -37 V. The device incorporates internal thermal overload protection, short-circuit current limiting, and output transistor safe area compensation. Designed for floating operation in high-voltage applications, it requires only two external resistors to set the output voltage. The component is housed in a standard TO-220 package.

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

Verify the specific suffix TU indicates the correct packaging configuration for your assembly process. Confirm that the manufacturer documentation explicitly lists KA337TU as the active part number rather than the generic LM337 or KA337 base designations. Ensure compliance with RoHS directives if required by your manufacturing standards. Cross-reference the datasheet revision date to confirm technical specifications match your design requirements.

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

Select this component when a reliable negative adjustable regulator is needed for currents above 1.5 A. The integrated protection features reduce the need for external safety components. Verify that the input voltage does not exceed the maximum rating relative to the output voltage. Consider the thermal resistance of the TO-220 package and ensure adequate heat sinking is available for continuous high-current operation.

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

The KA337TU belongs to the family of three-terminal negative adjustable regulators, functionally complementary to positive regulators like the LM317. Manufactured by onsemi, it shares architectural similarities with industry-standard parts such as the LM337 and KA337. The TO-220 package facilitates through-hole mounting and efficient heat dissipation, making it suitable for general-purpose power supply designs requiring negative voltage rails.
