S-1701A2825-M5T1G

Overview

The S-1701A2825-M5T1G is a dual-output fixed linear regulator from the ABLIC S-1701 series, housed in an SOT-23-5 surface-mount package. It provides two positive output voltages of 2.5 V and 2.8 V with a maximum continuous output current of 400 mA per channel. The device operates within an input voltage range of 2 V to 6.5 V and maintains a typical quiescent current of 85 µA. Key electrical specifications include a line regulation of 0.2 %/V, load regulation of 40 mV, and a dropout voltage of 140 mV at rated current. It supports power dissipation up to 420 mW and functions reliably across an industrial temperature range of -40 °C to +85 °C.
