ISL9000IRFCZ

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

The ISL9000IRFCZ is a dual-channel low-dropout linear regulator manufactured by Renesas Electronics Corporation. It integrates two independent positive fixed-output LDOs within a compact 10-lead VFDFN package measuring 3x3 mm. The device supports an input voltage range from 2.3 V to 6.5 V and provides fixed output voltages of 1.8 V and 2.5 V. Each channel delivers a maximum output current of 300 mA with a maximum dropout voltage of 0.4 V at full load. The IC features a typical quiescent current of 32 µA and includes integrated protection mechanisms such as overcurrent limiting, thermal shutdown, and under-voltage lockout.

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

Verify the specific suffix code to confirm exact output voltage combinations, as the base part number covers multiple variants. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration. Check for end-of-life notices or obsolescence warnings, as availability may be restricted. Ensure the selected package matches the PCB footprint specifications for the 10-VFDFN form factor.

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

Select this component when dual isolated LDO outputs are required within a minimal board area constraint. The 300mA per channel rating suits moderate load applications without external pass transistors. Consider the 32µA quiescent current for battery-operated designs where standby power consumption is critical. Verify that the required output voltages match the available fixed options for this specific suffix.

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

This device belongs to the ISL9000 series of dual LDO regulators designed for space-constrained portable electronics. It succeeds earlier Intersil designs following the company's acquisition by Renesas. The series emphasizes low noise and high power supply rejection to support sensitive RF and analog sections in mobile platforms.

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

Direct replacements include other ISL9000 series variants with different output voltage suffixes. Cross-reference with newer Renesas PMIC families if lead times are critical due to potential obsolescence status.
