ISL9008IEKZ-T

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

The ISL9008IEKZ-T is a fixed-output low noise LDO voltage regulator manufactured by Renesas Electronics Corporation. It provides a fixed output voltage of 2.85 V 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 dropout voltage of 0.3 V at full load. It is housed in a compact 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 exact suffix 'IEKZ' against official Renesas documentation to confirm the specific output voltage and package variant, as suffixes define electrical and mechanical characteristics. Confirm availability status directly with authorized distributors, as this part number may be subject to discontinuation or lifecycle changes. Ensure the supplier provides valid traceability and authenticity guarantees for critical power management components.

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

Select this component when a fixed 2.85 V rail is required with minimal noise and low current consumption. Compare dropout voltage specifications against the minimum input voltage headroom available in the system design. Consider the SC-70-5 package size constraints and thermal dissipation capabilities relative to the expected load current and ambient temperature conditions.

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

The ISL9008 series belongs to Renesas's portfolio of low-dropout linear regulators designed for low-power applications. Originally developed under the Intersil brand, these devices are characterized by their low noise and high PSRR, making them suitable for powering noise-sensitive components in portable and industrial electronics.

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

Check for direct pin-compatible alternatives within the ISL9008 family with different output voltages if the 2.85 V specification does not match the target circuit requirements. Verify equivalent performance metrics such as noise density and PSRR when considering cross-brand replacements.
