Overview
The S-8341C25AFT-T2-U is a CMOS step-down switching regulator manufactured by ABLIC Inc. It operates within an input voltage range of 2.0 V to 6.0 V and provides a fixed output voltage of 2.5 V. The device utilizes pulse width modulation (PWM) control for stable regulation. Key electrical characteristics include a typical quiescent current of 17 µA and a maximum ripple current of 1.0 A. It functions reliably across an ambient temperature range from -40 °C to +85 °C and is housed in a compact SOT-23-5 package.
Feature Summary
- Integrates a power MOSFET for high efficiency and reduced external component count
- Employs PWM control mode to maintain stable output voltage under varying load conditions
- Features low quiescent current consumption to extend battery life in portable applications
Applications
- Portable electronic devices requiring efficient power management
- Battery-powered equipment utilizing single-cell lithium-ion or lithium-polymer sources
- General-purpose DC-DC conversion in consumer electronics
Procurement Notes
Verify the specific suffix T2-U against official ABLIC documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with standard SOT-23-5 footprint requirements during PCB layout. Cross-reference the part number with the latest datasheet revision to validate operating parameters and thermal characteristics before finalizing procurement orders.
Selection Notes
Select this component when a fixed 2.5 V output is required from a 2.0 V to 6.0 V input source. It is suitable for designs prioritizing low standby current and minimal external passive components. Consider the SOT-23-5 package constraints regarding thermal dissipation and available board space relative to alternative regulator topologies.
Part Context
This part belongs to the S-8341 series of step-down switching regulators designed for low-power applications. The series emphasizes high efficiency and small form factors, making it appropriate for space-constrained portable electronics. ABLIC integrates the control logic and power switch on a single chip to simplify circuit design.
Replacement Considerations
Consult official substitution guides for pin-compatible alternatives within the S-8341 family or other ABLIC step-down regulators. Verify that any substitute matches the 2.5 V output specification and SOT-23-5 package dimensions.
