ISL9008AIEJZ-T

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

The ISL9008AIEJZ-T is a single-output low-dropout (LDO) voltage regulator manufactured by Renesas Electronics. It provides a fixed output voltage of 2.8 V with a maximum continuous 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 280 mV at full load. It maintains a load regulation of 0.1% and offers high power supply rejection ratio (PSRR) performance. The component is housed in a SC-70-5 surface-mount package and is rated for operation between -40°C and +85°C.

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

Verify the specific suffix 'EJ' confirms the 2.8 V fixed output variant before procurement. Confirm that the SC-70-5 package dimensions match the target PCB footprint. Ensure the design accounts for the specified thermal dissipation limits within the operating temperature range. Check for end-of-life status as distribution availability may be limited.

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

Select this component when a compact, low-noise power source is required for battery-operated systems. The wide input voltage range supports various battery chemistries. The low quiescent current aids in extending battery life during standby modes. Verify that the required output current does not exceed the 150 mA continuous rating under worst-case thermal conditions.

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

This part belongs to the ISL9008A series of low-noise LDO regulators from Renesas. The series is designed for applications requiring clean power supplies in space-constrained environments. Similar variants in the family offer different fixed output voltages while sharing the same pinout and protection features.

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

Other ISL9008A variants with different output voltages are pin-compatible but provide different DC levels. Direct functional replacements must match the 150 mA current rating and SC-70-5 package. Verify that alternative LDOs meet the same noise and PSRR specifications for the specific application.
