ISL9000IRFCZ-T

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

The ISL9000IRFCZ-T is a dual-channel low-dropout linear regulator manufactured by Renesas Electronics Corporation. It integrates two independent 300mA LDOs within a compact 10-lead VFDFN package measuring 3x3mm with a height of 0.88mm. The device supports a wide input voltage range from 2.3V to 6.5V and provides fixed output voltages including 1.8V, 2.5V, and others. Key electrical specifications include a maximum dropout voltage of 0.4V at 300mA load, a typical quiescent current of 42µA, and high power supply rejection ratios reaching 90dB at 1kHz. It operates reliably across an extended temperature range of -40°C to +85°C.

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

Verify the specific suffix configuration against official datasheets to confirm exact output voltage combinations and tolerance grades. Confirm package marking details and moisture sensitivity levels prior to assembly. Ensure compatibility with RoHS and REACH regulations for your target market. Cross-reference pin assignments carefully during PCB layout design to prevent installation errors.

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

Select this component when designing systems that require dual isolated voltage rails from a single source. Evaluate the required output current against the 300mA limit per channel. Consider the input voltage range relative to the battery or supply source characteristics. Assess thermal dissipation requirements based on the voltage drop and load current in the intended application environment.
