ISL9001AIRKZ-T

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

The ISL9001AIRKZ-T is a single-output low dropout linear regulator manufactured by Renesas Electronics Corporation. It provides a fixed output voltage of 3V with a maximum output current of 150mA. The device operates within an input voltage range of 2.3V to 6.5V and features a typical dropout voltage of 200mV at full load. It is housed in an 8-lead DFN package and supports surface mount installation. The component functions across a temperature range of -40°C to +85°C.

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

Verify the specific suffix 'R' indicates the 3V fixed output variant, as the base ISL9001A series offers multiple voltage options. Confirm the 'KZ' package designation matches the required 8-lead DFN footprint for your PCB layout. Check current stock status as availability may vary by region. Ensure RoHS compliance documentation is obtained for regulatory requirements. Validate that the 150mA current rating meets your peak load demands.

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

Select this component when a fixed 3V rail is required from a 2.3V to 6.5V source. Choose this part over adjustable regulators if board space is limited and a fixed voltage is sufficient. Consider the 150mA limit against your maximum load current. Verify that the input voltage never exceeds the 6.5V maximum absolute rating. Ensure the application does not require higher current than the LDO can provide.

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

This part belongs to the ISL9001A family of high-performance low dropout regulators. The family is characterized by low standby current and high PSRR. Other variants in the series offer different fixed output voltages ranging from 1.5V to 3.3V. The series is designed for portable applications requiring efficient power management and clean voltage rails.

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

Direct substitutes include other ISL9001A variants with matching 3V output and 150mA capability. Verify pinout compatibility before replacing with similar LDOs from other manufacturers. Ensure replacement parts support the same 8-lead DFN package dimensions.
