Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for ISL9021IRUNZ-T

ISL9021IRUNZ-T

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

The ISL9021IRUNZ-T is a fixed-output linear low-dropout (LDO) voltage regulator manufactured by Renesas Electronics. It provides a fixed output voltage of 3.3 V with a maximum continuous output current of 250 mA. The device operates within an input voltage range of 1.5 V to 5.5 V and maintains a typical dropout voltage of 150 mV at full load. Quiescent current is specified at 50 µA, ensuring low power consumption during operation. The component is housed in a compact 6-UTDFN package measuring 1.6 x 1.6 mm.

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

Integrated reverse current protection prevents backflow from output to input, safeguarding the regulator in battery-backed applications.
Includes comprehensive internal protection mechanisms such as overcurrent limiting, thermal shutdown, and soft-start functionality.
Designed for high power supply rejection ratio (PSRR) performance to minimize noise coupling in sensitive analog circuits.

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

Portable electronic devices requiring stable low-noise power rails
Battery-powered systems utilizing reverse current protection
Embedded sensor modules needing precise voltage regulation

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

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm package marking and date codes against official datasheets. Request lot traceability documentation to ensure compliance with RoHS standards and historical manufacturing specifications prior to integration into production designs.

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

Select this regulator when a fixed 3.3 V output is required with minimal external component count. The 6-UTDFN package suits space-constrained layouts. Ensure input voltage remains within the 1.5 V to 5.5 V range to maintain regulation. Consider the 50 µA quiescent current for battery life calculations in low-power standby modes.

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

This component belongs to the ISL9021 series of single LDO regulators featuring low noise and high PSRR. The series offers various fixed output voltages and packaging options, including WLCSP and µTDFN formats. The ISL9021IRUNZ-T specifically denotes the 3.3 V variant in the 6-lead ultra-thin dual flat no-lead package.

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

Direct pin-to-pin replacements are limited due to the product's end-of-life status. Evaluate alternative LDOs from the same family with compatible output voltages and current ratings. Verify that substitute components support reverse current protection if required by the original design constraints.
