ISL9000IRBCZ

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

The ISL9000IRBCZ is a dual low dropout (LDO) voltage regulator manufactured by Intersil, now part of Renesas Electronics. It features two independent positive output channels housed in a compact 10-lead DFN package measuring 3x3 mm. The device provides fixed output voltages of 1.8 V and 3.3 V with a maximum output current of 3 A per channel. It operates within an input voltage range of 2.3 V to 6.5 V and supports junction temperatures from -40°C to +85°C. Key electrical characteristics include a typical dropout voltage of 200 mV at full load and high power supply rejection ratio (PSRR) performance.

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

Verify the specific suffix 'IRBCZ' against official Renesas/Intersil documentation to confirm pinout compatibility and thermal specifications. Confirm end-of-life status and availability through authorized distributors, as this component may be discontinued or superseded by newer series. Ensure RoHS compliance matches project requirements before finalizing procurement orders.

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

Select this component when dual isolated LDO outputs are required in a minimal footprint. The 3 A current capability suits high-power digital loads, while the low noise profile benefits sensitive analog circuits. Compare dropout voltage and PSRR requirements against alternative single LDO solutions if space permits. Verify input voltage headroom relative to the minimum 2.3 V start-up requirement.
