Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for ISL9021IRUPZ-T

ISL9021IRUPZ-T

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

The ISL9021IRUPZ-T is a fixed-output linear low-dropout (LDO) regulator manufactured by Renesas Electronics Corporation. It provides a fixed output voltage of 3.0V with a maximum continuous output current of 250mA. The device supports an input voltage range from 1.5V to 5.5V and features a typical dropout voltage of 0.25V at full load. Key electrical characteristics include a quiescent current of 50µA, high power supply rejection ratio (PSRR), and precise output regulation. It is housed in a compact 6-UTDFN package measuring 1.6x1.6mm.

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

Integrated reverse current protection prevents backflow from the output to the input, ensuring safety for battery-powered applications.
Includes comprehensive protection mechanisms such as overcurrent limiting, thermal shutdown, and soft-start functionality.
Optimized for low-noise performance with high PSRR, suitable for sensitive analog and RF circuitry.

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

Portable consumer electronics requiring stable power rails
Battery-operated devices needing efficient power management
RF modules and sensors demanding low noise regulation

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

Verify the specific suffix 'IRUPZ-T' against official Renesas documentation to confirm pinout and tolerance specifications. Check for End-of-Life (EOL) status or Last-Time-Buy notices, as older Intersil/Renesas parts may have limited availability. Ensure compatibility with RoHS3 standards if required for your manufacturing process.

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

Select this component when a fixed 3.0V rail is required with minimal external components. Consider the 250mA current limit and 5.5V maximum input voltage constraints. The 6-UTDFN package offers a small footprint but requires adequate thermal relief on the PCB due to the exposed pad design.

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

This part belongs to the ISL9021 series of single LDO regulators known for low quiescent current and high PSRR. Originally developed by Intersil before its acquisition by Renesas, the series includes various output voltages and package options like WLCSP and µTDFN. The IRUPZ-T variant specifically denotes the 3.0V fixed output in the 6-lead ultra-thin dual flat no-lead package.

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

Direct substitutes within the same family include ISL9021AIRUCZ-T (1.8V) or ISL9021AIRUNZ-T (3.3V) if voltage adjustment is acceptable. For equivalent performance with different packages, consider the ISL9021IIMZ-T in WLCSP format. Verify pin-to-pin compatibility before replacing.
