ISL9014IRNCZ

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

The ISL9014IRNCZ is a dual low-dropout (LDO) linear voltage regulator manufactured by Intersil, now part of Renesas Electronics. It provides two independent fixed output voltages with a maximum source 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 DFN-10 (3x3 mm) surface-mount package. Key electrical specifications include a typical dropout voltage of 200 mV at 150 mA, line regulation of 0.2%/V, and load regulation of 1%. It maintains a reference voltage of 1 V and ensures voltage accuracy of 1.8%.

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

Verify component authenticity through authorized Renesas channels due to the product's discontinued status. Confirm RoHS compliance and specific manufacturing lot dates as availability varies. Ensure compatibility with existing PCB footprints before procurement, as obsolete parts may require careful sourcing strategies to maintain supply chain stability for legacy systems.

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

Select this component when dual isolated outputs are required within a compact footprint. It is appropriate for designs where low noise and high PSRR are critical performance factors. Consider the 300 mA current limit per channel against total system load requirements. Evaluate thermal dissipation capabilities within the DFN-10 package relative to ambient operating conditions and board layout constraints.
