TLV73333P New 300mA Capacitorless LDO Regulator

01.05.2015

Texas Instruments' new low dropout TLV73333P series TLV733P integrated regulator is designed to operate in devices with current consumption up to 300 mA.

The TLV73333P provides a fixed output voltage of 3,3V and generally does not require any wiring to operate. Stable operation is ensured even without connecting an input and output capacitor, which can be useful in battery-powered applications where high starting currents must be avoided.

Despite the low price, the TLV73333P stabilizer has good parameters - the voltage drop at the maximum current is less than 122 mV, the internal consumption current is 34 μA, there is a control input and an automatic discharge mode of the output capacitance through a built-in 120 Ohm resistor. When the regulator is turned off, the current consumption is reduced to 100 nA, while the control current on the Enable line is only 10 nA.

The TLV73333P stabilizer has protection against overheating, short circuit and input voltage drop below a certain value.

The TLV73333PDBVT chip is available in the popular SOT-23-5 package. If you need to minimize the PCB, you can choose the 2x1 mm X1SON package (TLV73333PDQNR).

The TLV733P series includes integrated voltage regulators with low voltage drop and fixed output voltage from the range: 1,0; 1,1; 1,2; 1,5; 1,8; 2,5; 3,3 V.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Hidden identification with invisible QR codes 01.09.2023

A team of researchers from the Massachusetts Institute of Technology has introduced an innovative identification system called BrightMarker, which has unique properties. These tags, visible only in the infrared spectrum, open up new horizons in secure tagging and tracking technology, which is considered more reliable than the widespread traditional QR codes popularized amid the global coronavirus pandemic.

The essence of the technology lies in the introduction of unique marks into objects during their production using special fluorescent threads. It is important to note that these labels have absolutely no effect on the characteristics and functionality of objects. To detect such tags, a number of hardware devices have been developed that are easily integrated with smartphones and virtual reality headsets.

The researchers believe BrightMarker technology has potential for a variety of applications. Invisible tags can authenticate items and track their movements, while still providing the functionality of regular QR codes. However, it is worth noting that BrightMarkers can only be applied to objects created using XNUMXD printing, which limits their scope.
