ISL9014IRJRZ-T

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

The ISL9014IRJRZ-T is a dual-channel low-dropout (LDO) linear voltage regulator manufactured by Intersil. It features two independent positive fixed outputs, typically configured for 2.8V and 2.6V or 3.3V variants, delivering up to 300mA per channel. The device operates with an input voltage range of 2.3V to 6.5V and maintains a maximum dropout voltage of 0.325V at full load. Designed for low-noise applications, it incorporates high power supply rejection ratio (PSRR) characteristics. The component is housed in a compact 10-lead DFN (3x3mm) package with an exposed pad, suitable for surface-mount assembly.

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

Verify the specific suffix and manufacturing date code carefully, as this component series has reached end-of-life status with limited availability from primary sources. Confirm RoHS compliance and lead-free specifications against current inventory batches. Ensure the supplier provides valid traceability documentation due to the discontinued nature of the part. Cross-reference pinouts and electrical parameters with the official datasheet to avoid compatibility issues with legacy designs.

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

Select this component when dual isolated LDOs are required within a constrained board area. The 300mA output current per channel supports moderate load requirements without external pass transistors. Consider the fixed output voltage options available in the series to match system rail requirements directly. The DFN package offers thermal advantages but requires adequate PCB copper pour for heat dissipation during operation.
