ISL9014IRPLZ-T

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

The ISL9014IRPLZ-T is a dual-output low-dropout (LDO) linear voltage regulator manufactured by Intersil, now part of Renesas Electronics. It provides fixed output voltages of 1.85 V and 2.9 V with a maximum output current of 300 mA per channel. The device operates within an input voltage range of 2.3 V to 6.5 V and features a typical dropout voltage of 300 mV at full load. It is housed in a compact 10-lead DFN package (3x3 mm) with an exposed pad for thermal management. The regulator supports operation from -40°C to +85°C and includes internal circuitry for low noise and high power supply rejection ratio (PSRR).

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 RoHS compliance status and specific lot traceability before integration. Check for obsolescence notices as the product may be subject to lifecycle changes. Ensure proper handling procedures are followed during storage and assembly to maintain device integrity.

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

Select this component when dual isolated LDO outputs are required in a minimal footprint. Consider the 300 mA current limit per rail against system load demands. Evaluate the fixed voltage options against target logic levels. Assess thermal performance based on PCB copper area and ambient conditions given the DFN package characteristics.

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

This part belongs to the ISL9014 series of low-power LDO regulators. It shares functional similarities with other dual-output LDOs but is distinguished by its specific voltage combinations and noise performance. The series targets applications where size and efficiency are critical. Intersil's expertise in precision analog design informs the internal reference and pass transistor architecture used in this family.

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

Direct substitutes include the ISL9014IRBJZ-T variant which offers different fixed output voltages (1.5 V and 2.8 V) while maintaining similar electrical characteristics and pinout compatibility. Verify that the alternative voltage levels meet the specific circuit requirements before substitution.
