The TPS76533D is a three-terminal, low-power linear voltage regulator designed for general-purpose, voltage level shifting and voltage control applications. The device provides an adjustable output voltage range from 1.0 V to 14 V with an output current capability of 0.1 A. It is designed using Bipolaron Technology, and the internal low resistance/low power architecture allows it to be used in a variety of applications, especially when space is a premium. In addition, the wide input voltage range and low noise output voltage, make the TPS76533D perfectly suited for powering low-noise architectures, such as power amplifiers or audio circuits.

The TPS76533D is available in the SOT223-4 package and is a simple, three-pin solution for low-power linear voltage regulation applications. The device has a wide input voltage range from 3.0 V to 28 V and offers features such as short-circuit protection, over-temperature protection, output current limiting, and reverse-voltage protection. With these features in place, the device provides excellent thermal stability and line/load transient response.

The TPS76533D is ideal for applications such as portable devices, mobile phones, notebooks, and other applications that require reliable, low-power linear voltage regulation. It can also be used to replace many obsolete power supply designs, and can increase energy efficiency and reduce operational costs.

The TPS76533D voltage regulator has the following features:

• Wide input voltage range of 3.0 V to 28 V.
• Output voltage range of 1.0 V to 14 V.
• Output current capability of 0.1 A.
• Built-in short-circuit protection.
• Built-in over-temperature protection.
• Built-in output current limiting.
• Easily configurable for various applications.
• Low power architecture allows for use in space-constrained applications.
• Wide input voltage range and low noise output voltage make it perfect for powering low-noise architectures.

The TPS76533D works by providing a constant output voltage that is referenced to the “ADJ” pin. When the voltage at the “ADJ” pin is greater than the external reference voltage, the output voltage will be increased by an equal amount. The amount of adjustment is determined by the “GAIN” pin voltage, with a 100 mV change at the “GAIN” pin resulting in a 1.0V change at the output. The device can also be configured for an inverted mode, providing a negative output voltage.

In addition to the adjustable version, the TPS76533D is also available in pre-programmed versions, providing fixed output voltages of 5.0 V, 6.5 V, 8.3 V and 10.5 V. The device requires only a few external components and is easily configured for various applications.

In summary, the TPS76533D offers a cost-effective and space-saving solution for applications requiring low-noise and adjustable, or pre-programmed, linear voltage regulation. It provides an adjustable output voltage range from 1.0 V to 14 V and is ideal for powering audio circuits or other low-power devices with demanding voltage regulation requirements.
