LM2586T-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2586T-5.0/NOPB is a SIMPLE SWITCHER step-up, flyback, or forward regulator IC from Texas Instruments. It operates with an input voltage range of 4V to 40V and provides a fixed 5V output at up to 3A switching current. The device utilizes current-mode control for rapid transient response and inherent overcurrent protection. It is housed in a TO-220-7 through-hole package, supporting junction temperatures from -40°C to 125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'NOPB' confirms lead-free and RoHS compliance per Texas Instruments specifications. Ensure the ordering part number matches the exact package variant (TO-220-7) and fixed output voltage (5.0V). Cross-reference the manufacturer datasheet revision to confirm pinout compatibility and electrical characteristics before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output is required from a 4V to 40V input source using a non-isolated topology. It is suitable for designs prioritizing simplicity and cost-effectiveness over high-frequency miniaturization. Consider the thermal performance of the TO-220 package for heat dissipation requirements in the target application environment.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2586 family of SIMPLE SWITCHER regulators, designed for easy implementation of DC-DC conversion circuits. The 'T' indicates the TO-220 package, while '5.0' specifies the fixed 5-volt output version. The 'NOPB' designation signifies that the component is manufactured without lead and complies with environmental standards set by the original equipment manufacturer.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct functional substitutes include other LM2586 variants with different output voltages or packages, such as the LM2586SX-5.0/NOPB for surface-mount applications. Verify pin-to-pin compatibility and thermal resistance differences when replacing with alternative package styles or adjusted voltage outputs within the same product family.
