Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for ISL9021IRUTZ-T

ISL9021IRUTZ-T

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

The ISL9021IRUTZ-T is a single-output fixed linear low-dropout (LDO) voltage regulator manufactured by Renesas Electronics Corporation. It provides a fixed output voltage of 3V with a maximum continuous output current of 250mA. The device operates within an input voltage range of 1.5V to 5.5V and features a typical dropout voltage of 150mV at full load, with a maximum specified dropout of 250mV. It utilizes a 6-lead Ultra Thin Dual Flat No-Lead (UTDFN) package measuring 1.6mm x 1.6mm. The component supports surface-mount installation and functions reliably across an extended industrial temperature range from -40°C to +85°C.

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

Integrated reverse current protection mechanism specifically designed for WLCSP and 1.6mm x 1.6mm 6-lead µTDFN packages to prevent backflow.
High power supply rejection ratio performance providing 75dB attenuation at 10kHz and 50dB at 1MHz for effective noise filtering.
Comprehensive internal protection circuitry including overcurrent limiting, thermal shutdown, reverse polarity blocking, and soft-start functionality.

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

Portable battery-powered consumer electronics requiring stable low-noise power rails
Wireless communication modules needing high PSRR for signal integrity
Embedded systems utilizing microcontrollers or sensors sensitive to voltage fluctuations

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

Verify the exact suffix configuration against official Renesas documentation, as variations in tape-and-reel packaging or lead finish may exist. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration. Ensure the selected variant matches the required output voltage tolerance and package dimensions for your specific PCB layout constraints.

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

Select this component when a compact footprint is critical due to its small 1.6mm x 1.6mm package size. Choose this LDO if the application demands high power supply rejection to minimize ripple on sensitive analog or RF circuits. Consider this part for designs requiring robust reverse current protection to safeguard upstream power sources during system shutdowns.

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

This device belongs to the ISL9021 series of low-power LDO regulators known for combining low quiescent current with high performance metrics. The series is engineered for applications where space is limited and electrical noise must be minimized. It serves as a key power management solution in portable devices where battery life and signal purity are primary design drivers.

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

Publicly confirmed substitute part numbers for ISL9021IRUTZ-T were not identified in available documentation. Verify compatibility with alternative LDOs based on pinout, voltage rating, and package dimensions before substitution.
