ISL8010IUZ

Voltage Regulators - DC DC Switching Regulators Overview

The ISL8010IUZ is a monolithic synchronous step-down regulator with integrated FETs, manufactured by Renesas Electronics Corporation. It operates within an input voltage range of 2.5V to 5.5V and delivers up to 600mA output current. The device features internal compensation and supports adjustable output voltages. It is housed in a 10-TFSOP or 10-MSOP package (0.118", 3.00mm width). Key electrical parameters include a quiescent current of 120µA and a switching frequency of 1.5MHz.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Battery-powered applications using Li-Ion sources

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix (e.g., T7, T13) against your bill of materials, as packaging varies. Confirm availability status, as this component may be subject to end-of-life notices or limited stock. Ensure the 10-pin MSOP/TSSOP footprint matches your PCB layout constraints before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact, low-current buck converter is needed for inputs between 2.5V and 5.5V. The internal compensation reduces BOM count compared to non-compensated alternatives. Consider the 1.5MHz switching frequency for trade-offs between inductor size and efficiency. Verify thermal performance for the intended load current in the chosen package.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to Renesas' ISL8010 series of monolithic synchronous step-down regulators. It is designed for space-constrained applications requiring efficient DC-DC conversion from common low-voltage rails. The integration of control logic and power switches distinguishes it from discrete solutions.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for direct pin-compatible replacements if available. Verify that any substitute maintains the 600mA current rating and 2.5V-5.5V input range. Ensure the replacement supports the required 1.5MHz switching frequency and internal compensation architecture.
