S-1701X3342-U5T1G

Special Purpose Regulators Overview

The S-1701X3342-U5T1G is a dual-output low dropout (LDO) voltage regulator from ABLIC, housed in an SOT-89-5 surface-mount package. It provides fixed output voltages of 3.3 V and 4.2 V with a maximum continuous output current of 400 mA per channel. The device features a typical quiescent current of 85 µA and a maximum dropout voltage of 380 mV at 100 mA load. It operates within a temperature range of -40 °C to +85 °C, offering line regulation of 0.2 %/V and load regulation of 40 mV.

Special Purpose Regulators Feature Summary

• Integrates two independent positive linear regulators in a single compact package for space-constrained designs.
• Combines voltage regulation with built-in voltage detection functionality for system monitoring capabilities.
• Maintains stable performance with ultra-low standby current consumption suitable for battery-powered applications.

Special Purpose Regulators Applications

• Portable electronic devices requiring multiple regulated supply rails
• Battery-operated systems needing efficient power management

Special Purpose Regulators Procurement Notes

Verify the specific suffix 'X' against official ABLIC documentation to confirm pinout and electrical characteristics, as variations exist within the S-1701 series. Ensure compatibility with SOT-89-5 footprint requirements. Confirm RoHS compliance status through manufacturer datasheets prior to integration into production environments.

Special Purpose Regulators Selection Notes

Select this component when dual isolated outputs are required from a single input source. Compare dropout voltage specifications against minimum input voltage constraints. Evaluate thermal dissipation capabilities based on expected load currents and ambient operating temperatures to ensure reliable long-term operation.

Special Purpose Regulators Part Context

The S-1701 series represents ABLIC's portfolio of high-efficiency LDO regulators designed for mobile and industrial applications. This model belongs to the combo voltage detector/regulator family, distinguishing it from standard single-output variants by integrating monitoring functions alongside power delivery.

Special Purpose Regulators Replacement Considerations

Direct substitutes include S-1701Y3342-U5T1G and S-1701E3026-U5T1G, which share identical packaging and general electrical profiles but differ in specific output voltage combinations.
