Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for SCT71401F33TWDR

SCT71401F33TWDR

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The SCT71401F33TWDR is a low-dropout linear regulator from the SCT71401 series, designed for input voltages ranging from 3V to 40V with a 45V transient tolerance. It delivers a fixed 3.3V output at up to 150mA. The device features a typical quiescent current of 2.5µA and supports output capacitance between 3.3µF and 220µF. It includes integrated short-circuit protection with over-current foldback (OCFB) and thermal shutdown.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

Wide input voltage range supporting 3V to 40V operation
Ultra-low quiescent current suitable for battery-powered applications
Integrated over-current foldback and thermal protection mechanisms

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Applications

Battery-powered portable devices
Microcontroller power supplies in always-on systems
CAN/LIN transceiver power regulation

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix 'F33TWDR' against official datasheets to confirm the fixed 3.3V output voltage and SOT-23-5 package configuration. Ensure compatibility with required output capacitance values (3.3µF–220µF) during integration. Cross-reference pinouts and thermal characteristics with manufacturer documentation before finalizing procurement decisions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component for designs requiring wide input voltage tolerance and low standby power consumption. The fixed 3.3V output eliminates external resistor networks. Consider the 2.5µA quiescent current for battery life optimization. Verify that the load current does not exceed 150mA and that the output capacitor ESR remains within the specified 0.001Ω to 5Ω range for stability.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the SCT71401 family of low-dropout regulators manufactured by Semitronix Technology Co., Ltd. The series is engineered for high-voltage input applications where standard LDOs may fail. The F33 variant specifically provides a regulated 3.3V rail, distinguishing it from other adjustable or fixed-voltage options within the same product line.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

The SGM2203 is documented as a compatible alternative within the same functional category. Verify pin-to-pin compatibility and electrical parameter alignment, particularly dropout voltage and quiescent current specifications, before substituting.
