ISL9000AIRNCZ-T

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

The ISL9000AIRNCZ-T is a dual-output low dropout (LDO) voltage regulator manufactured by Renesas Electronics. It provides fixed output voltages of 1.8 V and 3.3 V with a maximum output current of 300 mA per channel. The device operates within an input voltage range of 2.3 V to 6.5 V and features a typical dropout voltage of 400 mV at 300 mA load. It incorporates a reference voltage of 1 V, offers power supply rejection ratio (PSRR) of 90 dB at 1 kHz, and includes protection functions such as overcurrent, thermal shutdown, and under-voltage lockout.

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

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance and moisture sensitivity level (MSL 1) requirements during storage and handling. Ensure ordering suffix matches the tape-and-reel packaging specification for automated assembly processes.

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

Select this component when dual fixed outputs are required without external resistor networks. Evaluate input voltage headroom against the specified 2.3 V minimum and 6.5 V maximum limits. Consider the 10-DFN package dimensions for PCB layout constraints and thermal dissipation needs relative to the 300 mA per channel capability.
