LM2594PADJG

Voltage Regulators - DC DC Switching Regulators Overview

The LM2594PADJG is a monolithic integrated circuit step-down switching regulator manufactured by onsemi. It operates at a fixed frequency of 150 kHz and supports an input voltage range up to 40 V. The device provides an adjustable output voltage ranging from 1.23 V to 37 V with a guaranteed maximum load current of 0.5 A. It utilizes internal loop compensation to minimize external component requirements. The unit is housed in an 8-lead PDIP package and includes thermal shutdown and cycle-by-cycle current limit protection.
