ISL9001IRNZ-T

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

The ISL9001IRNZ-T is a single-output low dropout (LDO) linear voltage regulator manufactured by Renesas Electronics Corporation. It operates within an input voltage range of 2.3 V to 6.5 V and provides a fixed output voltage of 1.5 V. The device supports a maximum output current of 3 A with a typical dropout voltage of 200 mV at full load. It features a low quiescent current of 32 µA and high power supply rejection ratio (PSRR). The component 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 Procurement Notes

Verify the specific suffix 'IRNZ' against official Renesas documentation to confirm pinout compatibility and electrical tolerances. Confirm end-of-life status as distribution channels may list obsolete inventory. Ensure the ordering part number matches the required temperature grade and packaging format before finalizing procurement contracts.

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

Select this component when a single regulated rail is sufficient for the design requirements. Compare dropout characteristics against the minimum expected input voltage swing. Evaluate the thermal dissipation capabilities of the 10-DFN package under maximum load conditions. Verify that the 3 A output capability aligns with peak transient demands of the target application circuit.

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

This device belongs to the ISL9000/ISL9001 series of low-noise LDO regulators designed for portable applications. It shares architectural similarities with other members of the family but differs in output configuration, offering a single channel instead of dual outputs. The series targets markets demanding high performance in small form factors.
