ISL9008AIETZ-T

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

The ISL9008AIETZ-T is a single-output fixed linear voltage regulator from the ISL9008A series, manufactured by Renesas/Intersil. It provides a nominal output voltage of 1.9 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 quiescent current of 66 µA. Key electrical specifications include a maximum dropout voltage of 0.5 V at full load, a line regulation of 0.1%, and a load regulation of 0.8%. It is housed in a SC-70-5 surface-mount package and supports an operating temperature range from -40°C to +85°C.

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

This component is officially classified as obsolete by the manufacturer. Production has ceased, and no new units are available from primary sources. Procurement must rely on existing stock from authorized distributors or third-party suppliers. Verify authenticity and storage conditions carefully due to the end-of-life status. Lead times and availability are subject to market fluctuations rather than manufacturing schedules.

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

Select this part only if a fixed 1.9 V output is required and the obsolete status is acceptable for the design lifecycle. Ensure the input voltage remains above 2.3 V and does not exceed 6.5 V. Consider the 150 mA current limit and thermal dissipation in the SC-70-5 package. Evaluate alternative active components if long-term supply continuity is critical for the product roadmap.

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

The ISL9008A series consists of low-dropout regulators designed for low-noise applications. This specific model, ISL9008AIETZ-T, is one variant among several fixed-output options, including 1.8 V, 2.75 V, and 3.0 V versions. All variants share similar electrical characteristics and packaging but differ in their fixed output voltage settings.

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

No public confirmed substitute part numbers are documented in the provided source material. Due to the obsolete status, direct replacements may require functional equivalents with compatible voltage, current, and package specifications.
