ISL9008IENZ-T

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

The ISL9008IENZ-T is a low-noise, low-quiescent current linear voltage regulator (LDO) manufactured by Intersil. It features a single fixed output of 3.3 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 maintains a typical dropout voltage of 300 mV at full load. It offers high power supply rejection ratio (PSRR) and ultra-low noise performance. The component functions reliably across an extended temperature range 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 'IENZ' against official Renesas/Intersil documentation to confirm pinout, thermal characteristics, and RoHS compliance status. Confirm that the SC-70-5 package matches your PCB footprint design. Check for end-of-life or obsolescence notices as this component may be discontinued. Ensure static-sensitive handling procedures are followed during assembly due to the small form factor.

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

Select this component when a fixed 3.3 V output is required with minimal noise impact on signal integrity. It is suitable for applications where input voltages vary between 2.3 V and 6.5 V. Consider the 150 mA current limit for load requirements. Compare quiescent current specifications against other LDOs if battery efficiency is critical. Verify that the SC-70-5 package size fits within the available board space constraints.

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

The ISL9008 series represents Intersil's line of low-noise LDO regulators optimized for portable applications. The ISL9008IENZ-T specifically denotes the 3.3 V fixed output variant in the SC-70-5 package. This part belongs to a family designed to provide clean power for noise-sensitive components in mobile and handheld devices.

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

Check for direct cross-references in Renesas product transition guides. Alternative LDOs must match the 3.3 V output, 150 mA current rating, and SC-70-5 package. Verify compatibility of pinouts and electrical characteristics such as PSRR and dropout voltage before substitution.
