Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for ISL9021AIRUFZ-T

ISL9021AIRUFZ-T

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

The ISL9021AIRUFZ-T is a fixed-output positive low-dropout (LDO) voltage regulator manufactured by Renesas Electronics Corporation. It provides a stable 1.5 V output with a maximum continuous current of 250 mA. The device features a typical dropout voltage of 0.25 V at full load and maintains a low quiescent current of 35 µA. It operates within an input voltage range of 1.5 V to 5.5 V and supports an ambient temperature range from -40°C to +85°C. The component is housed in a compact 6-lead uTDFN package measuring 1.6 x 1.6 mm.

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

Integrated protection mechanisms including overcurrent, thermal shutdown, reverse polarity, short-circuit, and soft-start capabilities.
Designed for high power supply rejection ratio (PSRR) performance to minimize noise in sensitive analog circuits.
Utilizes a small footprint surface-mount package suitable for space-constrained portable applications.

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

Portable consumer electronics requiring efficient power management
Battery-powered devices needing low quiescent current operation
RF modules and sensors requiring low-noise voltage regulation

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

Verify the specific suffix and tape-and-reel quantity against official Renesas documentation before ordering. Confirm that the requested part number matches the exact output voltage and package type required for your design. Check for any recent Product Change Notifications regarding packaging or labeling updates. Ensure compatibility with your assembly process specifications.

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

Select this component when a fixed 1.5 V rail is needed with minimal board space. Consider the 250 mA limit for load requirements and verify input voltage stability above the dropout threshold. Evaluate the thermal performance within the 1.6 x 1.6 mm package for your specific power dissipation needs.

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

This LDO belongs to the ISL9021 series, which offers various fixed output voltages and packages. The 'AIRU' designation indicates the automotive/industrial temperature grade and the uTDFN-6 package style. This series is designed for applications prioritizing low noise and high PSRR alongside compact form factors.

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

Consult official Renesas cross-reference guides for verified substitutes. Ensure replacement parts match the 1.5 V output, 250 mA current rating, and uTDFN-6 package dimensions. Verify identical pinout configurations to prevent PCB redesign.
