Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for ISL9021AIRUWZ-T7A

ISL9021AIRUWZ-T7A

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

The ISL9021AIRUWZ-T7A is a single-output, positive fixed voltage linear regulator (LDO) manufactured by Renesas Electronics Corporation. It provides a fixed output of 1.2V with a maximum output current of 250mA. The device supports an input voltage range up to 5.5V and operates within a temperature range of -40°C to +85°C. It features low quiescent current and includes comprehensive protection mechanisms such as overcurrent, thermal shutdown, reverse polarity, short circuit, and soft start capabilities.

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

Single-output positive fixed voltage linear regulation
Integrated protection against overcurrent, thermal overload, reverse polarity, and short circuits
Soft start functionality for controlled power-up sequences

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

Portable battery-powered electronic devices
Low noise analog circuit power supplies
Embedded system voltage regulation

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

Verify the specific suffix 'T7A' corresponds to the required tape and reel packaging configuration. Confirm that the 1.2V output variant matches the design requirements, as the ISL9021 series offers multiple fixed voltage options. Ensure compatibility with the 6-UTDFN(1.6x1.6) package footprint during PCB layout. Check for end-of-life status or alternative recommendations from the manufacturer.

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

Select this component when a stable 1.2V rail is required from inputs up to 5.5V with moderate current demands. The low quiescent current makes it suitable for energy-efficient designs. Consider the small 6-UTDFN package size for space-constrained applications. Verify that the dropout voltage characteristics meet the minimum input-to-output differential requirements of the specific application circuit.

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

This part belongs to the ISL9021A series of low-dropout regulators from Renesas. The series is characterized by high power supply rejection ratio (PSRR) and low noise performance. The ISL9021AIRUWZ-T7A specifically denotes the 1.2V output version in the automotive-grade or industrial-grade A-series lineup, packaged in a compact 6-lead ultra-thin dual flat no-lead format.

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

Direct substitutes include other ISL9021 variants with different fixed output voltages if the voltage level can be adjusted, such as ISL9021AIRUCZ-T7A (1.8V) or ISL9021AIRUFZ-T7A (2.5V). Cross-reference with Renesas' current portfolio for pin-compatible LDOs if this specific part is discontinued.
