ISL9000AIRBCZ

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

The ISL9000AIRBCZ is a dual low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics Corporation. It provides two independent positive fixed output channels, typically configured for 1.2V and 1.8V outputs, within a compact 10-lead VFDFN package measuring 3mm x 3mm. The device supports an input voltage range from 2.3V to 6.5V and delivers up to 300mA per channel. Key electrical characteristics include a maximum dropout voltage of 400mV at full load, a quiescent current of 32µA, and high power supply rejection ratio (PSRR). Integrated protection features include overcurrent limiting, thermal shutdown, and undervoltage lockout (UVLO), alongside individual Power-On-Reset (POR) functions for each output.

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

Verify component authenticity through authorized distributors due to potential availability constraints. Confirm the specific output voltage configuration matches the design requirements, as suffixes denote different fixed voltage combinations. Check for end-of-life status or obsolescence notices from Renesas before finalizing procurement plans to ensure long-term supply stability.

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

Select this component when a dual-output LDO with low noise and high PSRR is required in a small footprint. Ensure the input voltage remains above the minimum threshold while accounting for dropout voltage under maximum load conditions. Verify that the total power dissipation stays within the thermal limits of the 10-lead DFN package for the intended operating environment.
