TPS7333QDR is a member of the Texas Instruments TPS7333 device family of low-voltage, low-dropout (LDO) linear voltage regulators. It is an integrated 3.3-V voltage regulator that operates from an input voltage of 1.3 V to 5.5 V with ultra-high-current capability of 500 mA. It provides very low quiescent current of 150 nA and offers output noise rejection of up to 90 dB.

The TPS7333QDR is a positive voltage regulator and is ideal for applications that require high-accuracy, low-power, low-dropout voltage regulation. It offers a wide range of features and benefits including low noise, low output impedance, low dropout voltage and high current capability. Its output is adjustable over a wide input voltage range and can be set in the range of 1.2 V to 90 V.

In terms of application fields, the TPS7333QDR is widely used in a variety of applications, such as systems that require low noise and high accuracy, as well as for power supply monitoring, low-noise audio, automotive and cellular applications. It also can be used in point-of-load and digital signal processor (DSP) systems. Moreover, systems integrated with radio frequency (RF) and microwave applications such as communication systems, radars and GPS systems also use TPS7333QDR.

The TPS7333QDR utilizes a unique structure to obtain a stable, low-noise, low-dropout voltage regulation of up to 90 V, with ultra-high output current capabilities. It features two complementary, high-efficiency power transistors, with low resistance for maximum efficiency. The two transistors act in parallel to provide the IC with ultra-high output current capabilities.

The TPS7333QDR also monitors the charge pump in order to maintain the output voltage in the desired range. When the output voltage is too high, the device turns off the charge pump to reduce the current flow, thereby reducing the output voltage. Similarly, when the output voltage is too low, the device increases the current flow to increase the output voltage.

In addition to voltage regulation, the TPS7333QDR also provides advanced current protection, including short circuit protection, thermal overload and excess current protection, overvoltage protection and reverse voltage protection. It also has a high EMI/RFI noise immunity of up to 90 dB, which makes it ideal for use in RF applications.

The TPS7333QDR is a robust voltage regulator with a wide range of features and benefits that makes it suitable for a variety of applications. Its low output impedance ensures the high accuracy of the output voltage, while its low quiescent current allows for low power consumption. Additionally, its wide input voltage range and current capability make it an ideal choice for applications that require high current. With its advanced protection features, the TPS7333QDR ensures a safe and reliable power supply for your applications.
