ISL9000IRKCZ

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

The ISL9000IRKCZ is a dual low-dropout linear regulator manufactured by Renesas Electronics Corporation. It integrates two independent LDOs, each capable of sourcing 300mA. The device operates with an input voltage range of 2.3V to 6.5V and features fixed output voltages of 1.8V and 2.85V. Key electrical parameters include a typical dropout voltage of 200mV at 300mA, extremely low quiescent current of 42µA with both LDOs active, and very high power supply rejection ratio (PSRR) of 90dB at 1kHz. It utilizes a 10-lead 3mm x 3mm DFN package.

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

Verify component authenticity through authorized channels due to potential availability constraints. Confirm the specific suffix matches the required output voltage configuration. Check for end-of-life status or alternative package options if standard stock is unavailable. Ensure compliance with RoHS standards and moisture sensitivity levels during storage and handling.

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

Select this component when designing circuits requiring dual isolated rails from a single source. It is suitable for applications demanding low noise and high PSRR in space-constrained environments. Consider the 1µF to 10µF output capacitance stability requirements. Evaluate the need for external POR timing capacitors if precise reset sequencing is critical.

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

This part belongs to the ISL9000A series of dual LDO regulators designed for portable electronics. It shares architectural similarities with other Renesas low-power PMICs but is distinct in its dual-output configuration and specific voltage offerings. The DFN10 package allows for compact PCB layouts compared to larger SOIC alternatives.
