Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for ISL9003AIENZ-T

ISL9003AIENZ-T

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

The ISL9003AIENZ-T is a single-output low-dropout (LDO) linear voltage regulator manufactured by Renesas/Intersil. It provides a fixed 3.3V output with a continuous load current capacity of 150mA. The device operates within an input voltage range of 2.3V to 6.5V and features a typical dropout voltage of 200mV at full load. It incorporates a shutdown pin that reduces standby current to a maximum of 1µA. The regulator is stable with 1µF to 4.7µF ceramic output capacitors and includes soft-start, current limit, and thermal overload protection functions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

High power supply rejection ratio exceeding 90dB at 1kHz for effective noise filtering
Extremely low quiescent current of 31µA to minimize power consumption in active mode
Integrated shutdown control allowing standby current reduction to 1µA maximum
Built-in protection mechanisms including current limiting and thermal overload shutdown

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

Portable instruments and handheld medical devices
Personal digital assistants (PDAs) and smart phones
MP3 players and other portable multimedia devices

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

Verify component authenticity through authorized Renesas or Intersil distributors. Confirm the SC-70-5 package marking matches official datasheet specifications. Ensure the revision suffix aligns with current manufacturing standards. Request RoHS compliance documentation prior to procurement. Validate supplier authorization status to mitigate counterfeit risks.

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

Select this component when a fixed 3.3V rail is required with minimal noise sensitivity. The 150mA current rating suits moderate load applications. Verify input voltage stability remains within the 2.3V to 6.5V operational window. Ensure output capacitance falls between 1µF and 4.7µF for guaranteed stability. Consider the SC-70-5 footprint constraints during PCB layout design.

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

This part belongs to the ISL9003A series of low-noise LDO regulators. It shares architectural similarities with the ISL9003AIEMZ-T but utilizes a different surface-mount package configuration. The series emphasizes high PSRR and low IQ for battery-powered consumer electronics. It serves as a compact power management solution for space-constrained mobile designs.

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

The ISL9003AIEMZ-T is a documented alternative offering identical electrical performance in a µTDFN package. Verify pin compatibility and thermal dissipation requirements when substituting packages. Ensure the replacement maintains the same 3.3V fixed output and 150mA current capability.
