ISL9008AIECZ-T

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

The ISL9008AIECZ-T is a fixed-output low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics, formerly Intersil. It provides a fixed 1.8 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 quiescent current of 46 µA. It exhibits a maximum dropout voltage of 0.5 V at full load and maintains a voltage regulation accuracy of 0.8%. The component 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

Verify the specific manufacturer source, as production has transitioned from Intersil to Renesas Electronics. Confirm RoHS compliance status through official documentation. Check for end-of-life notifications or discontinuation notices, as availability may be limited. Ensure the SC-70-5 package matches your PCB footprint requirements. Validate humidity sensitivity level handling during assembly.

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

Select this component when a fixed 1.8 V rail is required with minimal noise impact on adjacent circuitry. The low quiescent current makes it suitable for battery-operated systems where standby power consumption is critical. Ensure the input voltage remains above the minimum threshold while accounting for dropout voltage under maximum load conditions. Verify that the thermal performance in the SC-70-5 package meets the application's dissipation needs.

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

This part belongs to the ISL9008A series of low-noise LDO regulators. The series offers various fixed output voltages and packages, including uTDFN6. The 'IEC' suffix typically denotes the SC-70-5 package variant. These regulators are designed for applications demanding high PSRR and low noise, distinguishing them from standard general-purpose LDOs.

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

Check for direct pin-compatible alternatives within the ISL9008 family offering different fixed voltages if system requirements change. Verify electrical parameter equivalence for any cross-manufacturer replacements, specifically focusing on noise spectral density and PSRR curves.
