ISL9008IEFZ-T

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

The ISL9008IEFZ-T is a fixed-output low noise LDO voltage regulator manufactured by Renesas Electronics Corporation. It provides a fixed output voltage of 2.5 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 0.3 V at full load. It is housed in a compact 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 suffix 'EF' confirms the 2.5 V fixed output variant, as the base model number denotes the family. Confirm the 'T' suffix indicates tape-and-reel packaging if required for automated assembly. Ensure the manufacturer is identified as Renesas or Intersil, as both names appear in historical documentation for this component lineage.

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

Select this component when a stable 2.5 V rail is required with minimal board space constraints. The SC-70-5 package offers a small footprint suitable for dense layouts. Consider the 150 mA current limit against peak load demands. The wide input voltage range allows compatibility with single-cell lithium batteries or higher intermediate bus voltages.
