ISL9014AIRJBZ-T

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

The ISL9014AIRJBZ-T is a dual low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics. It integrates two independent LDO channels within a single 10-lead DFN package, designed for applications requiring compact power management solutions. The device supports an input voltage range from 2.3V to 6.5V and provides fixed output voltages of 1.5V and 2.8V. Each channel delivers up to 300mA of output current with excellent load regulation and high power supply rejection ratio (PSRR). The component operates over an extended temperature range of -40°C to +85°C and includes features such as enable control, thermal shutdown, and overcurrent protection.

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

Verify the specific suffix 'JBZ' against official Renesas documentation to confirm exact output voltage combinations and packaging details, as suffixes often denote specific binning or tape-and-reel configurations. Confirm availability status through authorized distributors, as this part number may be subject to end-of-life notices or obsolescence. Ensure compatibility with your PCB footprint requirements for the 10-DFN package before finalizing procurement decisions.

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

Select this component when designing systems that require two distinct regulated voltages from a single source without occupying excessive board space. It is suitable for designs where low noise and high PSRR are critical for signal integrity. Consider the 300mA per channel limit to ensure it meets the peak current demands of your load. Verify that the required output voltages match the fixed options available in the AIRJ variant.

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

The ISL9014 series belongs to Renesas's portfolio of high-performance analog power management ICs. This family is characterized by its ability to provide stable regulation with minimal external components. The dual-output configuration allows designers to replace separate single-channel regulators, reducing component count and simplifying layout. The DFN package offers thermal efficiency and small form factor advantages for modern consumer electronics.

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

Check for direct substitutes within the ISL9014 family with different output voltage suffixes if the 1.5V/2.8V combination does not fit. Evaluate newer generations of dual LDOs from Renesas or other manufacturers offering similar pinouts and electrical characteristics. Ensure any replacement maintains the same package type and thermal performance to avoid redesigning the PCB.
