ISL9003AIEHZ-T

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

The ISL9003AIEHZ-T is a single-output fixed linear regulator (LDO) manufactured by Intersil, delivering a continuous output current of 150mA. It provides a fixed output voltage of 2.5V with an input voltage range from 2.3V to 6.5V. The device features extremely low quiescent current of 40µA and a maximum dropout voltage of 0.4V at full load. It includes protection functions such as overcurrent, thermal shutdown, soft-start, and UVLO, operating within a temperature range of -40°C to +85°C in a SC-70-5 package.

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

Verify the specific suffix 'E' against official datasheets to confirm package type and temperature grade alignment. Confirm manufacturer status as Intersil or Renesas Electronics to ensure component authenticity. Check RoHS compliance documentation for environmental regulatory adherence. Validate that the fixed 2.5V output matches system requirements before procurement.

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

Select this component when a low-noise LDO with high PSRR is required for portable electronics. Ensure the input voltage remains within the 2.3V to 6.5V range for proper operation. Verify that the 150mA output current capacity meets the load demands. Consider the SC-70-5 package size for space-constrained PCB layouts.

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

This part belongs to the ISL9003 family of low-dropout regulators designed for low-power applications. It shares architectural similarities with other Intersil LDOs but is distinguished by its specific 2.5V fixed output and SC-70-5 packaging. The series targets battery-powered devices requiring efficient power management and stable voltage regulation under varying load conditions.
