Voltage Regulators - DC DC Switching Regulators datasheet and documents for L7986TR

L7986TR

Voltage Regulators - DC DC Switching Regulators Overview

The L7986TR is a synchronous step-down switching regulator from STMicroelectronics, featuring an embedded power MOSFET with a minimum current limit of 3.7 A to deliver up to 3 A output current. It operates with an input voltage range of 4.5 V to 38 V and provides an adjustable output voltage from 0.6 V to V_IN. The device includes an internal 250 kHz oscillator, programmable up to 1 MHz, and utilizes a VFDFPN-EP-10 package for efficient thermal management.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrates a 3.7 A current-limited embedded power MOSFET for high DC output current delivery
Features an internal 250 kHz switching frequency oscillator that can be externally adjusted up to 1 MHz
Supports low dropout operation with 100% duty cycle and zero load current capability
Includes built-in overcurrent and thermal protection mechanisms

Voltage Regulators - DC DC Switching Regulators Applications

Automotive digital instrument clusters
Industrial automation control systems
General-purpose DC-DC conversion in power management ICs

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix TR indicates tape and reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) prior to assembly. Ensure the ordering part number matches the required package variant, as L7986A denotes HSOP EP while L7986TR specifies VFDFPN-EP-10. Cross-reference datasheet revisions for any pinout or electrical parameter updates.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact buck converter solution is required for automotive or industrial environments. The exposed pad packages facilitate reduced thermal resistance, making it suitable for space-constrained designs. Consider the programmable switching frequency for optimizing external component size and EMI performance relative to system noise requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

The L7986TR belongs to the L7986 family of monolithic buck converters designed by STMicroelectronics. This series targets high-reliability applications in automotive and industrial sectors. The TR suffix specifically identifies the VFDFPN-EP-10 surface-mount package variant, distinct from the HSOP8 package found in other family members like the L7986A.
