S-8340A30AFT-T2-U

Overview

The S-8340A30AFT-T2-U is a CMOS step-up switching regulator manufactured by ABLIC Inc. It operates with an input voltage range of 900 mV to 10 V and provides a fixed output voltage of 3 V. The device delivers an output current of up to 282 mA at a switching frequency of 250 kHz. It features ultra-low standby current of 3 µA and supports operation from -40°C to +85°C in an SOT-23-5 package.

Feature Summary

• CMOS step-up topology for efficient DC-DC conversion
• Ultra-low standby current consumption
• Fixed output voltage regulation
• Wide input voltage operating range

Applications

• Portable electronic devices requiring battery boosting
• Sensor power supply circuits
• General purpose step-up voltage regulation

Procurement Notes

Verify the specific suffix T2-U against official ABLIC documentation to confirm package type and tape/reel specifications. Ensure compatibility with the required input voltage range and load current demands. Cross-reference the exact part number with authorized distributors to avoid obsolete or counterfeit components.

Selection Notes

Select this component when a fixed 3 V output is required from a low-voltage source. The 250 kHz switching frequency allows for smaller external inductors compared to lower-frequency alternatives. Verify that the 282 mA output current meets the peak load requirements of the target application circuit.

Part Context

This part belongs to the S-8340 series of CMOS step-up switching regulators. The series is designed for versatile applications requiring high-efficiency DC-DC conversion from low input voltages. It integrates reference voltage sources and control logic within a compact footprint suitable for space-constrained designs.

Replacement Considerations

Check for S-8340 variants with different output voltages if system requirements change. Verify pinout compatibility before substituting with other boost converters from ABLIC or third-party manufacturers.
