ISL9003AIRUMZ-T

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

The ISL9003AIRUMZ-T is a low-dropout linear voltage regulator manufactured by Renesas Electronics Corporation. It provides a fixed output voltage of 3V with a maximum continuous output current of 150mA. The device operates within an input voltage range suitable for single-cell lithium-ion battery applications and maintains regulation across a junction temperature range from -40°C to +85°C. Key electrical characteristics include a quiescent current of 46µA and a typical dropout voltage of 200mV at full load. The component is housed in a compact 6-UTDFN surface-mount package.

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

Verify the specific suffix 'T' indicates tape-and-reel packaging if required for automated assembly. Confirm RoHS compliance status through official datasheets as regulatory requirements may vary by region. Check for End-of-Life notifications or Production Discontinuation Notices, as availability may be limited. Ensure the 6-UTDFN footprint matches the design layout constraints.

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

Select this component when a fixed 3V rail is needed with minimal static power consumption. The 150mA current capability suits moderate load applications. Consider the 200mV dropout voltage against the minimum input voltage available in the system. The UTDFN-6 package offers a small board area but requires adequate thermal management for sustained high loads.
