ISL9014IRFDZ-T

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

The ISL9014IRFDZ-T is a dual-output low-dropout (LDO) linear regulator manufactured by Renesas/Intersil, housed in a DFN-10 package. It provides fixed positive output voltages of 2V and 2.5V with a maximum continuous output current of 150mA per channel. The device operates within an input voltage range of 2.3V to 6.5V and supports an operating temperature range from -40°C to +85°C. Key electrical characteristics include a typical dropout voltage of 250mV at 150mA for the first channel and 300mV at 150mA for the second channel. Line regulation is specified at 0.2%/V, while load regulation is maintained at 1%. The quiescent current is typically 45µA when both LDOs are active.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Integrates two independent high-performance LDO channels capable of sourcing 150mA each.
• Features extremely low quiescent current consumption for extended battery life.
• Provides high Power Supply Rejection Ratio (PSRR) suitable for noise-sensitive applications.
• Includes separate enable pins for individual control of each LDO output.

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

• Biasing analog circuits in industrial instrumentation systems

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

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm that the specific suffix matches the required output voltage configuration and package type. Ensure compliance with RoHS directives and check for moisture sensitivity level requirements during storage and handling. Validate lead times as supply status may vary.

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

Select this component when a compact dual-rail solution is needed for low-noise analog or digital loads. Compare against the ISL9014AIRFDZ-T if higher accuracy or different voltage options are required. Consider the ISL9014IRBJZ-T if higher current capacity up to 1A is necessary. Evaluate thermal performance based on PCB copper area and ambient conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the ISL9014 series of dual LDO regulators designed for low-power applications. It shares architectural similarities with other Intersil LDOs but is distinguished by its specific fixed voltage outputs and 150mA current rating. The DFN-10 package allows for space-constrained designs compared to larger SOIC packages.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Check for pin-compatible alternatives such as the ISL9014AIRFDZ-T for updated specifications. Verify functional equivalence with ISL9012 or ISL9011 series parts if current requirements differ. Ensure substitute components meet the same thermal and electrical performance criteria.
