ISL6414IR

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

The ISL6414IR is a triple-output, low-noise Low Dropout (LDO) regulator featuring an integrated reset circuit. It provides three fixed output voltages: LDO1 at 2.8V with 125mA capability, LDO2 at 2.8V with 125mA capability and typical dropout of 125mV at load, and LDO3 at 2.8V with 125mA capability and typical dropout of 100mV at load. LDO3 offers ultra-low noise, typically less than 30µV for VCO supply applications. The device operates stably with small ceramic output capacitors and is housed in a low-profile 4x4mm QFN package.

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

Verify the specific suffix and temperature grade against the official datasheet to ensure compatibility with your design requirements. Confirm availability status as Intersil products may be discontinued or subject to last-time buy notices. Cross-reference pinouts and electrical characteristics with the latest Renesas documentation before finalizing procurement.

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

Select this component when a compact solution for triple 2.8V regulation is required alongside reset monitoring. Ensure input voltage exceeds the maximum dropout voltage plus 2.8V. Verify that the load current does not exceed 125mA per channel. Consider the thermal performance within the 4x4mm QFN package under expected operating conditions.

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

This part belongs to the Intersil (now Renesas) family of low-power PMICs designed for portable electronics. It consolidates multiple power management functions into a small form factor, reducing PCB area compared to discrete solutions. The integration of LDOs and reset logic simplifies board layout and improves system reliability in space-constrained designs.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Check for direct pin-to-pin replacements from Renesas or other manufacturers offering similar triple-output LDOs with reset. Verify equivalent noise specifications, particularly for the VCO supply rail, and ensure compatible output capacitor requirements for stability.
