ISL9005AIRJZ-T

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

The ISL9005AIRJZ-T is a single-output low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics Corporation. It operates within an input voltage range of up to 6.5V and provides a fixed output voltage of 1.8V with a maximum load current of 300mA. The device features a typical dropout voltage of 400mV at full load and maintains a load regulation of 0.1%. It includes built-in protection mechanisms such as overcurrent limiting, thermal shutdown, and undervoltage lockout. The component is housed in a compact 10-lead DFN package measuring 3mm x 3mm and is rated for operation between -40°C and +85°C.

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

Verify the specific suffix AIRJZ-T against official Renesas documentation to confirm pinout compatibility and electrical specifications. Confirm end-of-life status and lead times with authorized distributors. Ensure ESD handling procedures are followed during storage and assembly due to moisture sensitivity classification.

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

Select this component when a fixed 1.8V rail is required with moderate current demands up to 300mA. Consider its small footprint for space-constrained designs. Evaluate the dropout voltage characteristics against your minimum input voltage requirements to ensure regulation stability under all operating conditions.

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

This part belongs to the ISL9005A series of low-power LDO regulators designed for portable applications. It shares architectural similarities with other members like the ISL9005AIRCZ-T but differs in package type and specific output configurations. The series emphasizes low quiescent current and high PSRR for noise-sensitive environments.

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

Direct substitutes include the ISL9005AIRCZ-T for similar performance in different packaging. Verify pin-to-pin compatibility before replacement. Cross-reference with newer Renesas PMIC families if long-term availability is a concern.
