ISL9008AIRUJZ-T

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

The ISL9008AIRUJZ-T is a fixed-output low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics under the Intersil brand. It provides a fixed output voltage of 2.8 V with a maximum load current capability of 150 mA. The device operates within an input voltage range of 2.3 V to 6.5 V and features a typical dropout voltage of 200 mV at full load. It is housed in a compact 6-pin UTDFN package with an exposed pad, designed for surface-mount installation. The component supports an operating temperature range from -40°C to +85°C and includes internal protections such as thermal shutdown and current limiting.

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

Verify the specific suffix 'AIRUJZ' against the official Renesas datasheet to confirm the 2.8 V fixed output and UTDFN-6 package configuration. Ensure compatibility with moisture sensitivity levels and reflow soldering profiles specified in the manufacturing guidelines. Confirm end-of-life status or obsolescence notices prior to final design approval.

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

Select this component when a fixed 2.8 V rail is required with minimal footprint and low noise characteristics. Compare dropout voltage and PSRR specifications against alternative LDOs if input voltage margins are tight. Consider the UTDFN-6 package thermal dissipation capabilities relative to the expected load current and ambient temperature conditions.

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

This part belongs to the ISL9008A series of low-noise LDO regulators. The family offers various fixed output voltages and packaging options, including SC-70-5 and UTDFN-6. The AIRUJZ variant specifically denotes the 2.8 V output version in the smaller 6-pin UTDFN package, distinguishing it from other voltage codes and form factors within the same product line.

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

Check for direct pin-compatible alternatives within the ISL9008 family with different output voltages if system requirements change. Verify electrical equivalence with newer Renesas LDO generations before substituting.
