ISL9014IRJNZ-T

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

The ISL9014IRJNZ-T is a dual-output low-dropout (LDO) linear regulator manufactured by Renesas/Intersil. It provides fixed positive output voltages of 1.5 V and 2.8 V with a maximum continuous output current of 1 A per channel. The device operates within an input voltage range of 2.3 V to 6.5 V. Key electrical specifications include a typical dropout voltage of 250 mV at 150 mA and 300 mV at 300 mA, line regulation of 0.2 %/V, and load regulation of 1 %. It features a reference voltage of 1 V and maintains a quiescent current of approximately 45 µA when active. The component is housed in a 10-lead DFN-10 package and supports operation from -40 °C to +85 °C.

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

Verify the exact suffix configuration against official datasheets to confirm output voltage combinations and package type. Confirm RoHS compliance status and moisture sensitivity level prior to ordering. Check for End-of-Life (EOL) notices or Product Change Notifications (PCN) as availability may be restricted. Ensure compatibility with existing PCB footprints and thermal design requirements before finalizing procurement decisions.

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

Select this component when dual isolated LDO outputs are required within a compact surface-mount footprint. Verify that the input voltage remains above the minimum threshold while accounting for dropout voltage at maximum load. Consider the thermal dissipation capabilities of the DFN-10 package relative to the expected power loss. Ensure the application benefits from the low quiescent current and high PSRR characteristics compared to standard regulators.
