L6986H5VTR

Voltage Regulators - DC DC Switching Regulators Overview

The L6986H5VTR is a synchronous step-down switching regulator from STMicroelectronics, designed to deliver up to 2 A DC output current. It operates with an input voltage range of 4 V to 38 V and provides a fixed 5 V output. The device features a low quiescent current of 30 µA in Low Consumption Mode (LCM) at light loads. It supports adjustable switching frequencies between 250 kHz and 2 MHz and includes an embedded output voltage supervisor. The component is housed in an HTSSOP-16 package and is rated for operation temperatures from -40 °C to +150 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Synchronous rectification architecture ensures high efficiency at medium to heavy loads while maintaining compact application size through high switching frequency capability.
• Dual operational modes including Low Consumption Mode for maximizing idle efficiency and Low Noise Mode for constant switching frequency and minimized ripple.
• Integrated output voltage supervisor manages reset phases for digital loads and enables output voltage sequencing during power-up via an open-collector RST output.

Voltage Regulators - DC DC Switching Regulators Applications

• Power supply systems for 5 V, 12 V, and 24 V industrial standards
• Programmable logic controllers (PLCs)
• Distributed intelligent nodes and sensor interfaces

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix H5VTR confirms the fixed 5 V output variant, as the L6986 series includes adjustable and other fixed voltage options. Confirm the HTSSOP-16 package designation matches your PCB footprint requirements. Ensure compliance with RoHS directives by checking the detailed specification sheet for environmental certifications before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required within a wide 4 V to 38 V input range. Choose the L6986H5VTR over adjustable variants if board space for external resistors must be eliminated. Consider the Low Noise Mode feature if the application demands minimal output voltage ripple, or utilize the Low Consumption Mode for battery-operated devices requiring extended standby life.
