ISL9008AIEFZ-T

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

The ISL9008AIEFZ-T is a fixed-output low dropout linear regulator manufactured by Renesas Electronics Corporation. It provides a stable 2.5 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 dropout voltage of 250 mV at full load. Quiescent current is specified at 46 uA, ensuring efficient power management in battery-powered applications. Voltage regulation accuracy is maintained at 0.8%, with a reference voltage of 1 V. The component supports operation from -40°C to +85°C and is housed in a compact SC-70-5 surface-mount package.

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

Verify the specific suffix 'EF' confirms the 2.5 V fixed output voltage variant before procurement. Confirm the 'Z' suffix indicates RoHS compliance and lead-free status as per Renesas standards. Check current lifecycle status, as this part may be subject to obsolescence or limited availability. Ensure ESD handling precautions are followed during assembly due to the small SC-70-5 package size.

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

Select this component when a fixed 2.5 V rail is required with minimal board space. Compare against adjustable variants if system flexibility is needed. Consider the 150 mA limit for load requirements. Evaluate thermal performance based on the expected voltage drop and ambient temperature conditions within the final enclosure.
