ISL9014AIRJCZ

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

The ISL9014AIRJCZ is a dual low-dropout linear regulator manufactured by Renesas Electronics Corporation. It provides two fixed positive output voltages: VO1 at 2.8V and VO2 at 1.8V. Each channel supports a continuous maximum output current of 300mA. The device operates with an input voltage range from 2.3V to 6.5V and maintains a typical quiescent current of 45µA when both LDOs are active. It features ±1.8% regulation accuracy, high power supply rejection ratio (70dB at 1kHz), and low output noise of typically 30µV RMS. The component is housed in a 10-lead 3mm x 3mm Dual Flat No-Lead (DFN) package and is rated for an operating temperature range of -40°C to +85°C.

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. Ensure proper handling procedures are followed due to electrostatic discharge sensitivity.

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

Select this component when a compact dual-rail power solution is required for portable electronics. It is suitable for designs needing simultaneous 2.8V and 1.8V rails with moderate current demands. Consider its low noise characteristics for analog sections and verify that the required output capacitance falls within the stable range of 1µF to 10µF.

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

What is the recommended output capacitor range for stability?

The device is stable with output capacitors ranging from 1µF to 10µF, provided the equivalent series resistance (ESR) is less than 200mΩ.

How does the device handle simultaneous enable signals?

If both enable pins are asserted simultaneously, the VO1 output has priority and powers up first. If one is asserted before the other stabilizes, the second output is delayed until the first reaches its target level.
