ISL9014AIRNFZ-T

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

The ISL9014AIRNFZ-T is a dual low-dropout (LDO) linear regulator manufactured by Renesas Electronics Corporation. It integrates two independent positive fixed-output regulators within a single 10-lead DFN package. Each output channel provides a maximum current of 300mA, with specific voltage configurations such as 3.3V and 2.5V available in the series. The device operates within an input voltage range of 2.3V to 6.5V and maintains a typical quiescent current of 40µA. It features a wide operating temperature range from -40°C to +85°C and includes comprehensive protection mechanisms.

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

Verify the exact suffix configuration against official datasheets, as variations exist within the ISL9014 family regarding output voltages and packaging types. Confirm component availability status, as certain variants may be discontinued or subject to end-of-life notices. Ensure compatibility with moisture sensitivity levels and reflow soldering profiles specified for the 10-DFN package during assembly planning.

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

Select this component when designing circuits that require two distinct regulated voltages from a single source without occupying excessive board space. Consider the 300mA per-channel limit to ensure it meets the peak load requirements of the downstream circuitry. Evaluate the dropout voltage characteristics relative to the minimum input voltage to maintain regulation under all operating conditions.
