ISL9000IRFDZ-T

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

The ISL9000IRFDZ-T is a dual-channel low-dropout linear regulator manufactured by Renesas Electronics. It integrates two independent 300mA LDOs within a compact 10-lead DFN package measuring 3x3mm. The device supports an input voltage range from 2.3V to 6.5V and provides fixed output voltages of 2V and 2.5V. Key electrical specifications include a maximum dropout voltage of 400mV at full load, a typical quiescent current of 42µA, and high power supply rejection ratios reaching 90dB at 1kHz. It operates reliably across a temperature range of -40°C to +85°C.

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

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration when sourcing. Confirm that the manufacturer has officially designated this part as limited availability or end-of-life status prior to finalizing procurement plans. Ensure compatibility with RoHS3 compliance requirements if mandated by your regional regulations. Cross-reference the exact output voltage options available for this specific reel variant.

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

Select this component when space constraints require a dual-output solution in a small footprint. It is suitable for applications demanding low noise and high PSRR without external filtering components. Consider the fixed output voltage options of 2V and 2.5V during initial design phases. Evaluate the thermal performance within the 3x3mm DFN package based on expected ambient temperatures and load currents.

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

This device belongs to the ISL9000 series of dual LDO regulators designed for portable applications. It replaces older discrete solutions by integrating two regulators into one chip. The series is characterized by its ability to maintain stability with small ceramic capacitors. It serves as a power management IC for systems requiring multiple regulated rails from a single source.

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

Check for direct pin-compatible alternatives within the same Renesas family. Verify if other suffixes like 'IRFCZ' offer identical electrical characteristics with different packaging. Ensure substitute parts match the required output voltage combinations and package dimensions.
