ISL9000IRKCZ

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

The ISL9000IRKCZ is a dual low-dropout (LDO) linear regulator from the Intersil ISL9000A series, manufactured by Renesas. It provides two independent fixed output voltages of 2.8V and 2.85V with a combined maximum output current of 3A per channel. The device operates within an input voltage range of 2.3V to 6.5V and features a typical dropout voltage of 200mV at 300mA load. It utilizes a 10-lead DFN-10 package and supports an operating temperature range from -40°C to +85°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Integrates two high-performance LDOs with very high power supply rejection ratio (PSRR) and low output noise for sensitive analog applications.
• Includes individual Power-On-Reset (POR) functions for each output, with externally programmable delay for the second channel via a timing capacitor.
• Features soft-start and staged turn-on capabilities to limit input current surge during enable, alongside current limit and overheat protection.

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

• Portable instruments and handheld devices requiring stable dual-rail power supplies
• Medical handheld equipment needing low-noise regulation
• Smartphones and PDAs utilizing multiple voltage domains

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

Verify component authenticity through authorized channels as this part may be subject to obsolescence or limited availability.
