ISL9000IRKFZ

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

The ISL9000IRKFZ is a dual-channel low-dropout linear regulator manufactured by Renesas Electronics Corporation. It integrates two independent positive fixed-output LDOs within a single 10-lead VFDFN package measuring 3x3 mm with a height of 0.88 mm. The device supports an input voltage range from 2.3 V to 6.5 V and provides a combined maximum output current of 300 mA per channel. Fixed output voltages are available in combinations such as 2.5 V/2.85 V. Key electrical parameters include a maximum dropout voltage of 0.4 V at 300 mA, a typical quiescent current of 32 µA, and a maximum supply current of 52 µA. The component operates reliably across a temperature range of -40°C to +85°C.

Ensure compatibility with standard RoHS compliance requirements for your manufacturing process.

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

Select this component when a dual-output solution is required to minimize board space and simplify power architecture. Consider the low quiescent current specification for battery-operated applications where standby power consumption is critical. Evaluate the input voltage range against your system's supply rails to ensure adequate headroom for the specified dropout characteristics. Verify that the thermal performance of the 10-VFDFN package meets the heat dissipation needs of your application.

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

This part belongs to the ISL9000 series of dual LDO regulators designed for portable electronics. It shares the same core architecture and pinout with variants like the ISL9000AIRKFZ-T but differs in specific output voltage configurations and tolerance grades. The series is characterized by its small footprint and integration of essential protection features, making it suitable for dense PCB layouts.

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

Direct substitutes include other parts within the ISL9000 family, such as the ISL9000AIRKFZ-T or ISL9000IRMMZ-T, provided they offer compatible output voltage pairs. Verify that any replacement maintains the same 10-VFDFN package dimensions and pin assignments to ensure mechanical interchangeability without redesigning the footprint.
