ISL9014IRFJZ-T

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

The ISL9014IRFJZ-T is a dual low-dropout (LDO) linear regulator manufactured by Intersil, now part of Renesas Electronics. It features two independent fixed positive outputs housed in a compact 10-lead DFN package measuring 3x3 mm. The device supports an input voltage range from 2.3 V to 6.5 V and provides a total output current capability of 300 mA per channel. Key electrical characteristics include a typical quiescent current of 45 µA with both LDOs active and less than 0.1 µA in shutdown mode. It offers high power supply rejection ratio (PSRR) and low noise performance, suitable for sensitive analog circuits.

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

Verify the specific suffix 'JZ' against official datasheets to confirm pinout and thermal pad configuration. Confirm RoHS compliance status as manufacturing processes may evolve. Check for End-of-Life (EOL) notices or last-time buy dates from Renesas distributors. Ensure the tape-and-reel packaging matches your automated assembly requirements.

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

Select this component when dual isolated rails are needed from a single source. Compare dropout voltages against your minimum input-output differential. Evaluate the need for external reference bypassing to optimize noise performance. Consider the 10-DFN package size constraints relative to your PCB layout density.

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

This part belongs to the ISL9014 family of dual LDO regulators designed for low-power, high-performance applications. It succeeds earlier single-output LDOs by integrating two channels in a small footprint. The series is characterized by its ability to maintain stability with ceramic capacitors while offering superior line and load regulation compared to standard regulators.

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

What is the maximum output capacitance allowed for stability?

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

How does the shutdown current compare to active quiescent current?

In shutdown mode, with both enable pins low, the device draws typically less than 0.1 µA, significantly lower than the 45 µa active quiescent current.
