ISL9000IRNCZ

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

The ISL9000IRNCZ is a dual low-dropout (LDO) linear voltage regulator manufactured by Intersil, now part of Renesas Electronics. It features two independent positive outputs housed in a 10-lead DFN package measuring 3x3 mm. The device supports an input voltage range from 2.3 V to 6.5 V and provides fixed output voltages including 2.8 V and 3.3 V. Each channel delivers up to 300 mA of output current with a typical dropout voltage of 200 mV at full load. It operates within a temperature range of -40°C to +85°C and includes integrated power-on-reset functions for each output.

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 the specific suffix indicates the correct output voltage configuration and package variant. Check for end-of-life status or obsolescence notifications prior to finalizing procurement plans. Ensure compliance with RoHS directives if required for the target market.

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

Select this component when designing circuits that require dual isolated rails with high noise immunity. It is suitable for systems where space is limited due to its compact DFN footprint. Consider the fixed output voltage options available in the series to match system requirements without external resistors. Evaluate the thermal performance given the small package size under maximum load conditions.

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

This device belongs to the ISL9000A series of high-performance dual LDOs designed for portable electronics. It complements other variants like the ISL9011 and ISL9012 which offer different current capabilities. The series is characterized by low quiescent current and excellent line/load regulation, making it a standard choice for powering analog front ends in consumer electronics.

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

Check for pin-compatible alternatives within the same family, such as ISL9000AIRNFZ or ISL9000AIRNJZ, ensuring identical output voltage combinations. Verify that any substitute maintains the same PSRR specifications and thermal characteristics. Confirm package dimensions match the existing PCB layout to avoid mechanical interference.
