ISL9000AIRGCZ-T

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

The ISL9000AIRGCZ-T is a dual-channel low dropout (LDO) linear regulator manufactured by Renesas Electronics Corporation. It integrates two independent high-performance LDOs within a single 10-lead VFDFN package measuring 3.00 x 3.00 mm with a height of 0.88 mm. The device provides fixed output voltages of 2.5V and 2.8V, each capable of delivering up to 300mA of output current. It operates with an input voltage range from 2.3V to 6.5V and maintains a maximum dropout voltage of 400mV at full load. Key electrical parameters include a typical quiescent current of 42µA when both channels are active, a power supply rejection ratio (PSRR) of 90dB at 1kHz, and an output noise of typically 30µV RMS. The component supports operation across an extended temperature range of -40°C to +85°C.

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

Verify the specific suffix 'GCZ' against official Renesas documentation to confirm exact output voltage combinations and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Check for obsolescence notices or product discontinuation announcements from the manufacturer. Ensure the ordering part number matches the required pinout and thermal pad configuration for your PCB layout.

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

Select this component when space-constrained designs require dual regulated outputs from a single IC footprint. It is suitable for applications demanding low static current to extend battery life while maintaining high line and load regulation. Consider the 10-lead DFN package for its thermal performance and small board area compared to traditional packages. Verify that the required output voltages match the available factory-fixed options.

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

This device belongs to the ISL9000A series of dual LDO regulators designed for portable electronics. It replaces older discrete regulator solutions by integrating two channels into one compact form factor. The series is characterized by low noise and high PSRR, making it ideal for powering RF front ends and digital logic simultaneously. Renesas acquired Intersil, which originally developed this family of power management ICs.

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

Check for direct cross-reference part numbers from Renesas or other manufacturers offering identical pinouts and electrical characteristics. Verify that any substitute component supports the same 300mA per channel output current and fits within the 3x3mm DFN footprint. Ensure replacement parts maintain similar PSRR and noise specifications if used in sensitive analog circuits.
