LM1501AGT-12

Voltage Regulators - DC DC Switching Regulators Overview

The LM1501AGT-12 is a monolithic integrated circuit step-down switching regulator manufactured by TAEJIN Technology. It provides a fixed 12V output voltage and is capable of driving a guaranteed 5A load current with excellent line and load regulation. The device operates at a fixed internal oscillator frequency of 300kHz, allowing for the use of small external components. It features an input voltage range up to 40V and includes low power standby mode with typical 80uA quiescent current. The component offers thermal shutdown and current limit protection, housed in a TO-263 package.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'GT' against official manufacturer documentation to confirm pinout compatibility and package variations. Ensure the fixed 12V output variant matches the system requirement, as other versions exist. Confirm lead times and availability directly with authorized distributors or the manufacturer, as supply chain conditions vary. Validate that the TO-263 package fits the target PCB footprint and thermal management strategy.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12V output is required from an input voltage up to 40V. It is suitable for applications needing up to 5A load current with minimal external component count. Consider the 300kHz switching frequency for trade-offs between efficiency and passive component size. Verify thermal requirements for the TO-263 package under maximum load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

The LM1501B series comprises monolithic step-down switching regulators designed for high-efficiency power conversion. Available in fixed outputs of 3.3V, 5V, 12V, and an adjustable version, the series supports up to 5A loads.
