S-1135A10-A6T1U Application Field and Working Principle

The S-1135A10-A6T1U Ultra Low Dropout (ULDO) Low Noise Linear Regulator is a member of Seiko Epson’s ULDO product family. Seiko Epson\'s unique A6T package with its minimal power loss with good thermal characteristics has become the go-to in applications requiring high quality Power Management Integrated Circuits (PMICs). This ULDO product family of PMICs includes high power systems, low power (micro-power) systems, and systems with capacitive loads.The S-1135A10-A6T1U ULDO is ideal for applications requiring a highly efficient regulator circuit. It can provide up to 1.6A of output current at a minimum dropout voltage of 0.4V. It has an adjustable output voltage the range of 0.50V to 8.0V and a fixed output voltage of 5.0V and 3.0V. This ULDO is designed for low noise, low power consumption and has a dropout voltage of less than 0.4V from 0.25A to 1.6A. It has a low noise (background noise) of -80 dbmV to -110 dbmV at the output. Additionally, it has a sophisticated anti-ringing circuit to prevent output noise that could otherwise affect the performance of the device it is powering.The S-1135A10-A6T1U ULDO is designed for use in a wide range of applications. Examples include wireless power supplies for portable computing and communications devices, base station power supplies, and industrial power supplies. It is suitable for use in handheld device power management, charge power management applications, automotive systems, and device power control & monitoring. In addition, the device is suitable for use in DC/DC conversion, battery driven circuits, and digitally controlled circuit applications.The excellent efficiency of the internal MOSFET of the S-1135A10-A6T1U ULDO allows this device to have a very low current consumption. This makes the ULDO suitable for use with low-voltage power sources such as USB ports, lithium-ion batteries, or solar cells.The main working principle of the S-1135A10-A6T1U ULDO is to control the flow of current by regulating the gate current. This gate current is supplied through a resistor from the output of the device to the gate of the MOSFET. The gate voltage is then sensed and compared to an internal reference voltage. If the two voltages are not equal, the output voltage is adjusted accordingly by changing the gate current.By utilizing a well-designed feedback control loop, the S-1135A10-A6T1U ULDO is able to maintain a stable output voltage even when the input voltage varies. The ULDO also provides over-voltage protection, over-temperature protection, and reverse-battery protection. Moreover, the low noise and low power consumption are further enhanced by an integrated power saving (PSAVE) mode.In summary, the S-1135A10-A6T1U ULDO is an efficient, low power, low noise device suitable for use in a variety of applications. Its unique A6T package minimizes power loss and offers excellent thermal characteristics. With its adjustable output voltage range and an integrated anti-ringing circuit, the S-1135A10-A6T1U ULDO is a reliable and cost-effective solution for power management applications.
