ISL9000IRJBZ-T

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

The ISL9000IRJBZ-T is a dual-output positive fixed linear low-dropout regulator manufactured by Renesas Electronics Corporation. It provides two independent output channels with fixed voltages of 1.5V and 2.8V, each capable of delivering up to 300mA of output current. The device operates within an input voltage range of up to 6.5V and features a maximum dropout voltage of 0.4V at full load. Key electrical specifications include a quiescent current of 32 µA and a maximum supply current of 52 µA. It is housed in a 10-DFN (3x3) surface-mount package with an exposed pad.

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

This component has been officially discontinued by the manufacturer as indicated by product discontinuance notices. Verification of availability should focus on surplus or secondary market sources rather than direct manufacturing orders. Engineers must confirm the specific revision status and ensure that any substitute components meet the original electrical and mechanical specifications before integration into new designs.

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

Designers should evaluate the fixed output configuration against system requirements, noting the specific 1.5V and 2.8V rails provided. The 300mA per channel limit dictates the maximum load capacity for connected peripherals. Thermal management considerations are necessary given the 10-DFN package size and the potential for heat dissipation under high load conditions. Verify that the input voltage remains within the specified maximum limits to ensure proper regulation and prevent damage.
