ISL9000AIRNJZ-T

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

The ISL9000AIRNJZ-T is a dual-output low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics. It operates within an input voltage range of 2.3 V to 6.5 V and provides fixed output voltages of 2.8 V and 3.3 V. Each channel supports a maximum output current of 300 mA. The device features a dropout voltage of approximately 200 mV at full load, with a typical quiescent current of 42 µA. It is housed in a compact 10-lead DFN (3x3 mm) package and is rated for operation between -40°C and +85°C.

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

• Dual-channel architecture providing independent 2.8 V and 3.3 V outputs from a single component.
• Low noise design optimized for sensitive analog and RF circuitry applications.
• Integrated protection mechanisms including overcurrent limiting, thermal shutdown, and undervoltage lockout.

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

• Powering mixed-signal systems requiring stable dual voltage rails.
• Biasing RF front-end modules in communication equipment.
• Supplying power to microcontrollers and memory devices in embedded systems.

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

Verify the specific suffix 'T' indicates tape-and-reel packaging versus 'Z' for tube. Confirm RoHS compliance status as the base series may have multiple environmental variants. Check for End-of-Life notices, as this part number is listed as obsolete or discontinued in several distributor records. Ensure the 2.8 V/3.3 V output combination matches the target design requirements before procurement.

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

Select this component when a dual LDO solution is required to save board space compared to using two separate regulators. The 300 mA output current is suitable for low-to-medium power loads. Consider the 2.3 V minimum input voltage constraint to ensure sufficient headroom for the desired dropout performance. Verify that the 10-DFN package footprint aligns with the PCB layout capabilities.

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

This device belongs to the ISL9000A family of low-noise LDO regulators. It shares the same core topology and pinout with variants offering different output voltage combinations, such as the ISL9000AIRNNZ (3.3 V/3.3 V) or ISL9000AIRNCZ (1.8 V/3.3 V). The family is designed for portable electronics and data communication applications where power efficiency and signal integrity are critical.

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

Direct functional substitutes include other ISL9000A variants with matching output voltages, such as ISL9000AIRNNZ for dual 3.3 V outputs. Cross-reference with newer Renesas PMIC families if the original ISL9000 series is fully discontinued. Ensure any replacement maintains the 10-DFN package dimensions for mechanical compatibility.
