ISL9008AIRUMZ-T

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

The ISL9008AIRUMZ-T is a fixed-output low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics, formerly Intersil. It provides a fixed 3 V output with a maximum load current 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 0.3 V at full load. It maintains a quiescent current of 46 µA and offers high power supply rejection ratio (PSRR) with low output noise. The component is housed in a 6-pin uTDFN package and supports an operating temperature range from -40°C to +85°C.

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

Verify the specific suffix 'AIRUMZ-T' against official Renesas documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for end-of-life notifications as this component may be discontinued or subject to obsolescence management protocols.

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

Select this component when a fixed 3 V rail is required with minimal footprint and low static current. Ensure input voltage remains above 2.3 V and does not exceed 6.5 V. Consider thermal dissipation capabilities within the uTDFN-6 package under expected load conditions. Verify that the 150 mA current limit meets system peak demands without triggering thermal shutdown.

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

This part belongs to the ISL9008A series of low-noise LDO regulators. It shares functional characteristics with other variants in the family but differs in output voltage, package style, and shipping configuration. The uTDFN-6 package offers a compact solution compared to SC-70-5 alternatives within the same product line.
