Texas Instruments LM2594 SIMPLE SWITCHER Power Converter 150 KHz 0.5A Step-Down Voltage Regulator LM2594N-12

The LM2594N-12 is a step-down voltage regulator from Texas Instruments, designed to provide a fixed output voltage of 12 V with a maximum output current of 0.5 A. It operates at a fixed frequency of 150 kHz and supports an input voltage range of up to 60 V. The device is available in an 8-pin PDIP package and requires only four external components for operation, simplifying the design process. This regulator features low power standby mode with a typical quiescent current of 85 OºA, thermal shutdown, and current-limit protection, ensuring reliable operation under various conditions. It offers a ¬±4% tolerance on output voltage across all line and load conditions, making it suitable for applications requiring stable voltage regulation. The LM2594N-12 is ideal for use in high-efficiency step-down applications, preregulators for linear regulators, and on-card switching regulators.
