Overview of TPS79428DCQR by Texas Instruments
The TPS79428DCQR is an innovative product from the well-established manufacturer Texas Instruments. This device is a low-dropout (LDO) regulator, which is a type of linear voltage regulator designed to provide high-efficiency power conversion. This capability allows devices to function effectively in environments with low input voltages, making this regulator a practical choice for many electronic systems.
Key Features of TPS79428DCQR
- High PSRR: The TPS79428DCQR boasts an impressive power-supply rejection ratio (PSRR), which is the ability of a device to maintain a constant output voltage despite variations in the input voltage. This feature makes the device particularly resilient in fluctuating power conditions.
- Low Noise: In terms of power output, the TPS79428DCQR is noted for its low noise operation, contributing to the efficiency and reliability of the overall system.
- High Output Current: With an output current capacity as high as 250mA, this regulator can power a wide range of devices, ensuring versatility of use.
Technical Specifications
The TPS79428DCQR is notable for its broad range of technical attributes. The device has a functional temperature range between -40°C to 125°C, making it resilient in various operating conditions. It is capable of delivering a high output current of 250mA. Moreover, the regulator's dropout voltage - the minimum amount by which the input voltage must exceed the output voltage to ensure the device operates correctly - is remarkably low, which is advantageous in low-power and battery-powered applications.
Applications of TPS79428DCQR
The TPS79428DCQR finds its uses in a diverse range of applications. Thanks to its high output current and low dropout voltage, it is particularly suited for battery-powered devices.
