ISL9012IRKFZ-T

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

The ISL9012IRKFZ-T is a dual low-dropout linear regulator manufactured by Renesas Electronics Corporation, housed in a 10-lead 3x3mm DFN package. It provides two independent positive fixed outputs: Channel 1 delivers up to 150mA and Channel 2 delivers up to 300mA. The device operates with an input voltage range of 2.3V to 6.5V and features a typical quiescent current of 45µA when both LDOs are active. It includes integrated Power-On Reset (POR) functionality for the VO2 output, adjustable via an external capacitor on the CPOR pin. The component supports separate enable pins for individual control and offers protection against overcurrent, thermal overload, and undervoltage lockout.

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

Verify that the specific ordering suffix matches the required tape and reel packaging configuration. Confirm the exact output voltage combination corresponds to the requested part number variant within the ISL9012 series. Ensure compatibility with the 10-lead 3x3mm DFN footprint during PCB layout. Check for any recent product change notices regarding manufacturing updates or material substitutions.

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

Select this component when a compact dual-output power solution is required for battery-operated portable electronics. Consider its low quiescent current for extended standby life and its ability to drive moderate load currents without excessive heat dissipation. Evaluate the need for the integrated POR function if system sequencing requires a reliable reset signal tied to the second output rail stability.

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

How is the Power-On Reset delay time determined?

The POR delay for the VO2 output is externally programmed by connecting a timing capacitor between the CPOR pin and ground. The delay duration scales proportionally with the capacitance value used.

What is the recommended output capacitance range for stability?

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