Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for ISL9021AIRUYZ-T7A

ISL9021AIRUYZ-T7A

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

The ISL9021AIRUYZ-T7A is a single low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics. It provides a fixed output voltage of 3.3V with a guaranteed continuous load current of 250mA. The device operates within an input voltage range of 1.5V to 5.5V and maintains high power supply rejection ratio (PSRR) performance, typically 75dB at 10kHz and 50dB at 1MHz. Quiescent current is specified at 35µA, with a maximum dropout voltage of less than 150mV at full load. Output accuracy is ±1.8% over temperature, line, and load variations. It functions reliably across an operating temperature range of -40°C to +85°C.

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

High PSRR performance for effective noise suppression in sensitive analog circuits
Low quiescent current consumption for extended battery life in portable devices

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

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific package marking codes against official datasheets before integration. Check for end-of-life notices or production change notifications that may affect long-term supply stability.

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

Select this component when a stable 3.3V rail is required from inputs as low as 1.5V. Ensure output capacitance remains between 1µF and 4.7µF with ESR within 5mΩ to 400mΩ for stability. Consider the 6-lead µTDFN package dimensions for PCB layout constraints.

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

This part belongs to the ISL9021A series of single LDO regulators designed for low-voltage, high-performance applications. The series offers various fixed output voltages and packages, including WLCSP and µTDFN options. It targets portable electronics requiring efficient power regulation with minimal noise impact on signal integrity.

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

Consult official substitution guides for equivalent parts within the ISL9021 family or compatible Renesas LDOs. Verify pin compatibility and electrical parameters such as dropout voltage and PSRR before replacing.
