ISL9014AIRKPZ

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

The ISL9014AIRKPZ is a dual low-dropout linear regulator manufactured by Renesas Electronics Corporation. It provides two fixed positive output voltages: VO1 at 2.85V and VO2 at 1.85V. Each channel supports a continuous maximum output current of 300mA. The device operates with an input voltage range from 2.3V to 6.5V. Quiescent current is typically 45µA when both LDOs are active, dropping below 0.1µA in shutdown mode. It features ±1.8% regulation accuracy over all operating conditions.

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

Verify the specific ordering suffix against official manufacturer documentation to confirm exact output voltage combinations and package variations. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability may vary based on production lifecycle stages.

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

Select this component for designs requiring dual independent regulated rails from a single source. Ensure input voltage remains within the specified 2.3V to 6.5V range. Verify that load requirements do not exceed the 300mA per channel limit. Consider the 10-lead DFN package dimensions for PCB layout constraints.

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

What is the typical output noise voltage for this device?

The typical output noise voltage is 30µV RMS measured at 100µA load with a 1.5V output and a 0.1µF bypass capacitor.

How does the device handle simultaneous enable signals?

If both enable pins are asserted simultaneously, the VO1 output has priority and powers up first before the VO2 output begins its ramp sequence.
