S-1701U3430-M5T1G

Overview

The S-1701U3430-M5T1G is a low dropout (LDO) voltage regulator from the ABLIC S-1701 series, featuring an integrated voltage detector. It provides two positive fixed output voltages: 3.4 V at up to 400 mA and 3.0 V at up to 260 mA. The device operates with a quiescent current of 85 µA and supports input voltages within its specified range. It utilizes a compact SOT-23-5 surface-mount package and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Combines dual-output LDO regulation with a built-in voltage detector in a single component
• Delivers high output current capability of 400 mA on the primary channel
• Maintains low power consumption with an ultra-low quiescent current of 85 µA
• Ensures stable operation in portable applications through wide operating temperature tolerance

Applications

• Battery-powered portable electronic devices requiring multiple stable voltage rails
• Embedded systems needing combined regulation and voltage monitoring functions
