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. It provides a stable 3 V output with a maximum continuous current of 150 mA. The device operates within an input voltage range of 2.3 V to 6.5 V and maintains a typical dropout voltage of 200 mV at full load. Quiescent current is specified at 46 uA, ensuring efficient power management in battery-powered applications. The component supports surface-mount installation in a compact UTDFN-EP-6 package and functions reliably across an industrial temperature range from -40°C to +85°C.

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

Verify the specific suffix 'AIRUMZ' against official Renesas documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status through the manufacturer's latest datasheet or environmental declaration. Check for End-of-Life (EOL) notices or last-time-buy dates, as this component may be subject to discontinuation. Ensure the ordering part number matches the required output voltage and package variant exactly.

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. Verify that the input voltage remains above the minimum threshold while accounting for dropout voltage under maximum load conditions. Consider thermal performance based on PCB copper area and ambient temperature constraints. Compare quiescent current and PSRR requirements against alternative LDOs if noise sensitivity is critical.

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

This device belongs to the ISL9008A series of low-noise LDO regulators designed for space-constrained applications.
