ISL9003AIEKZ-T

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

The ISL9003AIEKZ-T is a high-performance single low-noise, high PSRR LDO regulator from Intersil. It delivers a continuous 150mA load current with an input voltage range of 2.3V to 6.5V. The device features extremely low quiescent current of 31µA and typical dropout voltage of 200mV at full load. It operates within a temperature range of -40°C to +85°C and is housed in a 6-lead µTDFN package.

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

Verify the specific suffix 'IEKZ' against official Renesas/Intersil documentation to confirm package type and tape/reel specifications. Ensure compatibility with required output voltage options and thermal management requirements for the µTDFN footprint before finalizing procurement orders.

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

Select this component for applications requiring low noise and high PSRR in portable electronics. It is suitable where space is limited due to the small 6-lead µTDFN package. Consider the 150mA current limit and 2.3V minimum input voltage when designing the power stage.

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

This part belongs to the ISL9003 series of low-dropout regulators designed for portable consumer electronics. It shares functional similarities with other low-power LDOs but is distinguished by its specific package configuration and integrated shutdown capability, targeting mobile and handheld device markets.

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

Consult official substitution guides for equivalent LDOs with matching 150mA output and 6-lead µTDFN packages. Verify pin-to-pin compatibility and electrical parameter alignment before replacing.
