ISL9014IRLLZ-T

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

The ISL9014IRLLZ-T is a dual low-dropout linear regulator manufactured by Renesas Electronics Corporation. It provides two fixed positive output voltages of 2.9V each, with a continuous current capability of 300mA per channel. The device operates within an input voltage range of 2.3V to 6.5V and features extremely low quiescent current consumption of typically 45µA when both LDOs are active. It utilizes a compact 10-lead 3mm x 3mm Dual Flat No-Lead (DFN) package.

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

• Integrates two high-performance LDOs capable of sourcing 300mA from each output independently.
• Features separate enable pins for individual control of each LDO output with soft-start functionality.
• Includes integrated protection mechanisms such as current limit and thermal shutdown.
• Stable with ceramic output capacitors ranging from 1µF to 10µF.

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

• PDAs, Cell Phones and Smart Phones
• Portable Instruments and MP3 Players
• Handheld Devices including Medical Handhelds

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

Select this component for applications requiring dual independent power rails with low noise and high power supply rejection ratio. Suitable for battery-powered portable electronics where low standby current is critical. Verify that the required output voltage combination matches the specific suffix codes available in the ordering information table.

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

The ISL9014 series consists of dual LDO regulators designed for high performance in small packages. This specific part belongs to the standard ISL9014 family, distinct from the newer ISL9014A series which offers improved specifications. The device was originally produced by Intersil, now part of Renesas Electronics Corporation.

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

The datasheet explicitly recommends the ISL9014A as the replacement part for new designs. Verify if the ISL9014AIRLLZ variant meets the specific voltage and pinout requirements of the original design.

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

What is the typical quiescent current consumption?

The quiescent current is typically 45µA when both LDOs are enabled and active.

How does the device handle overheat conditions?

When the die temperature reaches approximately +145°C, one or both LDOs momentarily shut down until the die cools below +110°C, at which point they re-enable automatically.
