The S-1142CF0H-E6T2U is a low-noise, high-speed advanced low-dropout (LDO) linear voltage regulator with a range of features designed to address the stringent performance needs of modern applications. As part of Ricoh’s S-1142 family of LDO regulators, the S-1142CF0H-E6T2U offers a wide input voltage range of 2.7V to 15V and can provide an output voltage up to 14.25V with very good line regulation. It also includes a selectable current limiting values and a 250 mV dropout voltage.
Application Field and Working Principle
The S-1142CF0H-E6T2U is found in many applications, including GPUs, consumer electronic devices such as TVs, game consoles, and Blu-ray players, automotive power systems, laser printers, and wireless communication systems. This device works as an adjustable linear voltage regulator, regulated by the voltage values connected to the reference pins (VREF and FB pins). The output voltage is adjustable between a minimum and maximum level based on the voltage applied to the FB pin, which allows users to tailor the output voltage and current without increasing the voltage dropout.
The S-1142CF0H-E6T2U is designed to be used in systems requiring high efficiency and low power dissipation. The device is capable of providing a maximum load current of 500 mA, making it suitable for a variety of applications such as CPUs and memory devices. The low-noise feature also makes this device ideal for audio and media applications, providing a better audio experience while using less power.
The device also features current limit protection and thermal shutdown protection to ensure it remains stable and safe in all cases of over-current or over-temperature. The current limiting and auto-restart features of the S-1142CF0H-E6T2U ensure a safe operation by limiting the output current and automatically restarting the device once the fault condition has cleared.
The S-1142CF0H-E6T2U is considerably advantageous due to its very low quiescent current of only 0.9 μA, making it an ideal choice for ultra-low-power applications. This device also has very good line regulation values of 8 mV +/-2%, making it reliable for applications that require stability over a wide range of input voltages. Moreover, this device also provides excellent load regulation at 0.8% over the full load range, allowing for reliable operation even when the load is fluctuating.
Conclusion
The S-1142CF0H-E6T2U is a versatile low-noise, high-speed advanced LDO linear voltage regulator component that is designed to address the stringent performance needs of modern applications. This device is designed to provide low-power consumption, high efficiency and reliability while addressing the need for adjustable output voltage and current. Its low-noise feature make it an ideal choice for audio and media applications, while its current limit and thermal protection features ensure its safe and stable operation.
