ISL9008IECZ-T

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

The ISL9008IECZ-T is a fixed-output low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics Corporation. It provides a fixed output voltage of 1.8 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 dropout voltage of 300 mV at full load. It maintains a quiescent current of 46 uA and offers a voltage regulation accuracy of 0.8%. The component is housed in a SC-70-5 surface-mount package and is rated for operation over an extended temperature range from -40°C to +85°C.

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

Verify the specific output voltage variant, as the ISL9008 series includes multiple fixed voltage options. Confirm the package type matches the design requirements. Check the manufacturing date code and lifecycle status, as this component may be subject to obsolescence or discontinuation notices from Renesas. Ensure compliance with RoHS directives if required for the target market.

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

Select this regulator when a fixed 1.8 V output is required with minimal quiescent current draw. Consider the input voltage headroom relative to the dropout voltage under expected load conditions. Evaluate the thermal performance within the SC-70-5 package for the specific application environment. Compare PSRR specifications against the noise sensitivity of downstream components.

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

The ISL9008IECZ-T belongs to the ISL9008A family of low-noise LDO regulators designed for portable applications. This series emphasizes low power consumption and clean power delivery. The 'IECZ' suffix typically denotes the 1.8 V fixed output variant in the SC-70-5 package. Other variants in the family offer different fixed output voltages such as 1.5 V, 2.5 V, 2.75 V, 2.8 V, 2.85 V, 3.0 V, and 3.3 V.

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

Direct replacements include other ISL9008AIECZ-T units with identical 1.8 V output. Alternative fixed-voltage LDOs from Renesas or other manufacturers must match the 1.8 V output, 150 mA current rating, and SC-70-5 package footprint. Verify pin compatibility and electrical parameters before substitution.
