ISL9000AIRKPZ-T

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

The ISL9000AIRKPZ-T is a dual-output low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics Corporation. It integrates two independent 300mA LDOs within a compact 10-lead DFN package measuring 3mm x 3mm. The device provides fixed output voltages of 2.5V and 2.85V, operating with an input voltage range from 2.3V to 6.5V. Key electrical specifications include a typical dropout voltage of 200mV at full load, a quiescent current of 42µA, and high power supply rejection ratio (PSRR) of 90dB at 1kHz. The unit features ±1.8% accuracy over operating conditions and supports ceramic capacitors between 1µF and 10µF.

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

Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm RoHS compliance status and check for specific manufacturing date codes relevant to your production timeline. Ensure proper ESD handling procedures are followed during storage and assembly. Validate that the 10-DFN footprint matches your PCB design guidelines before finalizing procurement orders.

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

Select this component when dual isolated outputs are required from a single input source. The fixed 2.5V and 2.85V outputs suit specific logic families or analog reference needs. Consider the 300mA current limit for load requirements. The wide input range accommodates varying battery states. Verify thermal performance under maximum load conditions given the small package size.

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

This part belongs to the ISL9000A series of dual LDO regulators designed for space-constrained applications. It replaces older discrete solutions by integrating two regulators into one footprint. The series emphasizes low noise and high PSRR for sensitive analog circuits. Renesas continues to support this family for legacy designs requiring proven reliability.

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

Check for direct pin-compatible alternatives within the ISL9000 family offering different voltage combinations. Verify if newer Renesas PMICs offer integrated switching stages for higher efficiency. Ensure any substitute maintains the same 10-DFN package dimensions and thermal characteristics.
