LM2595TVADJG

Voltage Regulators - DC DC Switching Regulators Overview

The LM2595TVADJG is a 1.0 A step-down switching regulator from onsemi, operating at a fixed 150 kHz frequency. It accepts input voltages up to 40 V and provides an adjustable output voltage range of 1.2 V to 37 V with a maximum error of ±4%. The device utilizes a TO-220-5 through-hole package and includes internal frequency compensation and a fixed-frequency oscillator. It features TTL shutdown capability for low-power standby modes and incorporates thermal shutdown and current limiting protection.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated 150 kHz fixed-frequency oscillator allows for the use of smaller external filter components compared to lower-frequency regulators.
• TTL shutdown pin enables logic-level control for entering low-power standby mode with minimal quiescent current consumption.
• Built-in thermal shutdown and current limit protection enhance system reliability under fault conditions.

Voltage Regulators - DC DC Switching Regulators Applications

• Efficient buck converters for general-purpose power supplies
• Pre-regulators for linear regulators in high-efficiency designs
• On-board switching regulation for distributed power architectures

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation carefully, as the LM2595 part number is historically associated with Texas Instruments and National Semiconductor. Confirm that the specific 'onsemi' branding matches your supply chain requirements and quality standards. Ensure the TO-220-5 through-hole package aligns with your PCB footprint and assembly capabilities before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a robust, through-hole solution is required for 1 A step-down applications. The adjustable output variant offers flexibility for custom voltage rails between 1.2 V and 37 V. Consider the thermal performance of the TO-220 package for heat dissipation needs without additional heatsinking in moderate load scenarios.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the SIMPLE SWITCHER family of power converters, designed for simplicity and efficiency. The LM2595 series is widely recognized for its ease of implementation, requiring only four external components to establish a stable switching regulator circuit. It serves as a cost-effective alternative to more complex PWM controllers.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct functional equivalents include the LM2596T-ADJ (3 A version) or LM2595T-ADJ from Texas Instruments. Verify pin compatibility and thermal characteristics when substituting, as package variations may exist across different manufacturers producing similar legacy parts.
