The MAX1935ETA15+T is a very popular voltage regulator of the linear type. It is used in all kinds of diverse applications, including but not limited to, powering radio frequency equipment, supporting on-board low-voltage computer systems, and providing safe, reliable and efficient power to other electronic components. Here, we will go over the main details and the working principle of this voltage regulator. The MAX1935ETA15+T voltage regulator has an output voltage range of 0.7V to 13.6V, with a maximum current of 0.4A. It has an operating ambient temperature that ranges from 0° to 70°C and is compliant with the RoHS directive. In addition, it has a ripple rejection of 70 dB and a temperature drift of 0.05%.The most notable features of the MAX1935ETA15+T are its low noise (1.2 mV of noise at 0.1A load), low dropout voltage (150 mV at 0.1A load), very accurate output voltage (tolerance of ±0.5%), fast transient response time (500 ns), and very low quiescent current (20 µA). These features make it ideal for powering low-voltage systems on handheld devices.The MAX1935ETA15+T is also designed with an on-board compensation circuit that improves stability and reduces the effect of environmental changes on the system. This eliminates the need for an extra compensation network, allowing for more compact designs. The working principle of this linear voltage regulator is quite simple. It starts by accepting an input voltage that is greater than the output voltage and converting it to a lower output voltage. The voltage converter is based on a voltage controlling element, which is an NPN bipolar transistor. The current flowing through the shunting element is proportional to the base current flowing into the transistor, and this is also regulated by the shunt.The base current is regulated by the reference voltage, which is generated by a resistor divider network located between the input voltage and the shunt element. This reference voltage is compared to a voltage ramp generator and a sense amplifier. When the reference voltage is lower than the ramp voltage, the amplifier switches the shunt element to a high impedance, reducing the current flowing into the base of the transistor, and therefore reducing the output voltage. Conversely, when the reference voltage is higher than the ramp, the amplifier switches the shunt to a low impedance, allowing more current to flow into the base of the transistor, increasing the output voltage. The smooth and accurate regulation of the MAX1935ETA15+T makes it ideal for a wide range of applications. It is especially useful for powering low voltage systems found in many handheld devices. It has also been developed to reduce voltage droops, noise and electrical noise, and to provide extremely accurate output voltage control. Furthermore, due to its low quiescent current, fast transient response time, excellent ripple rejection and low dropout voltage, it can be used for powering radio frequency and other sensitive electronic components. In conclusion, the MAX1935ETA15+T is an ideal voltage regulator for powering low voltage systems in handheld devices, as well as providing a safe and reliable power supply for RF and other sensitive devices. It is a reliable device that has been designed to reduce noise, provide accurate output voltage control, and withstand environmental changes.
