ISL9001AIRCZ-T

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

The ISL9001AIRCZ-T is a single-output low dropout linear regulator manufactured by Renesas Electronics Corporation. It operates within an input voltage range of 2.3 V to 6.5 V and provides a fixed output voltage of 3 V with a maximum load current of 300 mA. The device features a typical quiescent current of 25 µA and a shutdown current of 0.1 µA. It exhibits high power supply rejection ratio (PSRR) of 90 dB at 1 kHz and low output noise of typically 30 µV rms. The regulator includes built-in current limit and thermal overload protection, along with a programmable delayed power-on reset (POR). It is designed for stability with ceramic output capacitors ranging from 1 µF to 10 µF.

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

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for specific annealing requirements indicated in the datasheet. Ensure proper handling procedures are followed due to surface mount packaging. Validate that the fixed 3 V output matches system design specifications before integration.

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

Select this component when a fixed 3 V rail is required with minimal static power consumption. The 8-lead DFN package suits space-constrained designs. Consider the 2.3 V minimum input voltage for battery-operated applications. The high PSRR makes it suitable for RF sections. Verify capacitor ESR requirements for stability with 1 µF to 10 µF ceramic outputs.

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

This part belongs to the ISL9001A series of low dropout regulators. It shares functional similarities with other members like the ISL9001AIRBZ-T but differs in output voltage configuration. The series is characterized by low IQ and high PSRR, targeting portable electronics. Renesas acquired Intersil, which originally developed this line, now supporting it under the Renesas portfolio.
