ISL9016IRUWJZ-T

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The ISL9016IRUWJZ-T is a dual low-dropout (LDO) voltage regulator manufactured by Renesas Electronics Corporation. It provides two independent positive fixed output channels, specifically configured for 1.2V and 2.85V outputs in this variant. Each channel supports a maximum continuous output current of 150mA. The device operates with an input voltage range up to 6.5V. Key electrical characteristics include a typical quiescent current of 67µA and a maximum dropout voltage of 0.425V at full load. It features high power supply rejection ratio (PSRR) and is stable with output capacitance ranging from 1µF to 4.7µF.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific output voltage configuration, as the ISL9016 family includes variants with different fixed output combinations such as 2.85V/2.85V or 1.2V/2.85V. Confirm package type compatibility, noting differences between UTDFN and UFDFN footprints. Check component status, as some variants may be discontinued or subject to product change notifications. Ensure ordering suffixes match the required electrical specifications and packaging options.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when dual isolated LDOs are required within a compact footprint. Evaluate the total output current requirements against the 150mA per channel limit. Consider the input-output voltage differential to ensure dropout specifications are met under all operating conditions. Verify that the load capacitance falls within the stable range of 1µF to 4.7µF to maintain stability without external compensation.
