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

The ISL9014AIRNCZ is a dual low-dropout linear regulator manufactured by Renesas Electronics Corporation. It integrates two independent LDOs capable of sourcing up to 300mA each, with fixed output voltages of 3.3V on VO1 and 1.8V on VO2. The device operates within an input voltage range of 2.3V to 6.5V and features extremely low quiescent current of 45µA when both outputs are active. It provides high power supply rejection ratio (PSRR) of 70dB at 1kHz and low output noise of 30µV RMS. Protection mechanisms include thermal shutdown, current limiting, and undervoltage lockout.

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

What is the typical quiescent current when both LDOs are active?

The typical quiescent current is 45µA when both LDOs are enabled and active.

How does the device handle simultaneous enable signals?

If both enable pins are asserted simultaneously, VO1 has priority and powers up first. VO2 turn-on is delayed until VO1 reaches its target level.
