ISL9014IRKJZ-T

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

The ISL9014IRKJZ-T is a dual low-dropout (LDO) linear regulator manufactured by Intersil, now part of Renesas Electronics. It operates within an input voltage range of 2.3 V to 6.5 V and provides two fixed positive output voltages of 2.8 V and 2.85 V. Each channel delivers up to 1 A of output current. The device features a DFN-10 package with dimensions of 3 mm x 3 mm and a maximum height of 0.9 mm. It supports an operating temperature range from -40°C to +85°C. Key electrical specifications include a line regulation of 0.2 %/V, load regulation of 1%, and dropout voltages ranging from 0.125 V at 150 mA to 0.4 V at 300 mA depending on the specific channel conditions.

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

• Dual independent LDO channels providing separate fixed voltage outputs for multi-rail power distribution.
• High performance design characterized by low noise and high Power Supply Rejection Ratio (PSRR).
• Low quiescent current consumption with typical standby current of 45 µA when both channels are active.
• Integrated thermal protection and overcurrent limiting to ensure reliable operation under fault conditions.

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

• Portable electronic devices requiring efficient multi-voltage power management.
• Battery-powered systems needing low standby current and high PSRR.
• Embedded applications utilizing single-cell lithium-ion or alkaline battery sources.

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

Verify component authenticity through authorized distributors as this part may be subject to obsolescence notices. Confirm package integrity upon receipt, as the DFN-10 form factor requires careful handling during soldering. Check for RoHS compliance documentation to ensure adherence to environmental regulations. Validate that the specific suffix matches the required output voltage configuration before integration into production designs.

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

Select this component when dual isolated rails are needed from a single input source with high current capability. Ensure the input voltage remains above the minimum threshold of 2.3 V while accounting for dropout requirements. Verify that the external capacitor values fall within the stable range specified in the datasheet. Consider the thermal dissipation capabilities of the DFN-10 package relative to the expected load current and ambient temperature conditions.

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

The ISL9014 belongs to the ISL901x family of dual LDO regulators designed for low-noise applications. It shares architectural similarities with the ISL9011 but offers higher output current capabilities. The series is optimized for portable electronics where space constraints and power efficiency are critical. The DFN-10 package allows for compact PCB layouts compared to traditional leaded packages.

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

Check for direct pin-compatible alternatives within the ISL9014 series such as ISL9014IRCJZ-T. Verify if the ISL9011 series meets current requirements despite lower amperage ratings. Confirm availability of equivalent parts from Renesas or licensed manufacturers due to potential end-of-life status.
