ISL9000AIRBLZ-T

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

The ISL9000AIRBLZ-T is a dual-output low dropout linear regulator from the Renesas ISL9000A series, housed in a 10-lead DFN (3x3 mm) package. It integrates two independent LDOs delivering fixed output voltages of 1.5 V and 2.9 V with a maximum continuous output current of 300 mA per channel. The device operates within an input voltage range of 2.3 V to 6.5 V and maintains a typical dropout voltage of 200 mV at full load. It features a reference voltage of 1 V, load regulation of 0.1%, and voltage regulation accuracy of 0.8%. The component supports operation across a temperature range of -40°C to +85°C.

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

Verify the specific suffix 'BL' confirms the 1.5V/2.9V output configuration before procurement. Confirm the 'R' indicates the industrial temperature grade (-40°C to +85°C). Ensure the 'Z' denotes RoHS compliance. Check current availability status as this part may be subject to discontinuation notices; consult official Renesas documentation for active lifecycle status and valid substitute recommendations.

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

Select this component when a dual-rail solution is required to minimize board space compared to using separate single regulators. It is suitable for applications demanding low noise and high PSRR without the complexity of switching converters. Verify that the total system current does not exceed the 300mA limit per channel. Consider the 10-DFN package constraints for thermal management if operating near maximum load currents.

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

This device belongs to the ISL9000A family of dual LDOs designed for portable applications. It shares architectural similarities with other variants like the ISL9000AIRBBZ-T and ISL9000AIRNNZ-T, differing primarily in fixed output voltage configurations. The series emphasizes low power consumption and small form factors, targeting mobile and handheld devices where battery life and PCB area are critical design constraints.

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

Publicly confirmed substitutes include the ISL9000AIRBBZ-T and ISL9000AIRNNZ-T. Verify that the alternative variant's output voltage ratings match the circuit requirements. Ensure the replacement maintains the same 10-DFN pinout and thermal characteristics to avoid redesigning the PCB layout.
