ISL78310ARAJZ

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

The ISL78310ARAJZ is a high-performance, single-channel low-dropout (LDO) voltage regulator manufactured by Renesas Electronics. It delivers a maximum output current of 1 A with an adjustable output voltage range spanning from 800 mV to 5 V. The device operates within an input voltage window of 2.2 V to 6 V and features a typical power supply rejection ratio (PSRR) of 72 dB. It exhibits a maximum dropout voltage of 212 mV and maintains line and load regulation at 1% and -1%, respectively. The component supports surface-mount installation in a DFN-10 package and functions reliably across an extended temperature range of -40°C to +125°C.
