The Texas Instruments TPS7H1101SPEVM is part of the family of high-efficiency, low-dropout linear voltage regulators evaluation boards designed for use in a variety of applications. This 120 mA, 1.2 V output, single LDO regulator evaluation board is one of the most efficient single-channel linear regulators available. It utilizes TI\'s internally compensated and highly efficient TPS7H1101 and TPS7H1201 LDOs, and its versatile design allows it to be used in either an adjustable or fixed output configuration. Using the adjustable configuration, the user can set the output voltage to a desired level and then optimize the loop response, while the fixed configuration requires setting the output voltage with a resistor divider.

Ideal applications for the TPS7H1101SPEVM evaluation board are systems that operate in the microcontroller environment such as wearable and mobile devices, personal medical appliances, and systems on chip. These evaluation boards permit the user to set the output voltage level as desired while providing precise regulation over temperature, line, and load. This makes them ideal solutions for battery powered and energy harvesting applications.

The TPS7H1101SPEVM demonstrates the use of linear voltage regulators in a variety of applications. The board is comprised of a low dropout regulator power stage, input and output filter capacitors, and various control circuitry. The power stage consists of a high-efficiency, low-noise TPS7H1101 and TPS7H1201 linear voltage regulator, specifically designed to power microprocessors with tight voltage regulation and excellent dynamic response. The input and output filter capacitors provide excellent ripple rejection and excellent transient protection. The control circuitry includes a power-on reset, over voltage protection, power good function, and an enabling signal for standby mode.

One of the primary features of the TPS7H1101SPEVM evaluation board is its low quiescent current, allowing it to operate efficiently in low-power applications. This is due to its integrated “low IQ” circuitry which reduces the quiescent current in standby mode, allowing for longer battery life. Additionally, the board has a programmable duty cycle frequency of up to 1.8MHz, making it suitable for high frequency applications such as mobile devices. The board also includes an “enable” pin which allows the user to easily put the board in a low-power, standby mode.

The TPS7H1101SPEVM is an ideal evaluation board for linear voltage regulators. It offers high efficiency, low-dropout performance, robust ripple rejection and excellent transient response. The board is easy to use and can be configured for either adjustable or fixed output operation. Its integrated “low IQ” circuitry efficiently reduces quiescent current, providing extended battery life in low-power applications. With its wide range of features and versatile design, the TPS7H1101SPEVM is the perfect choice for powering a variety of microcontroller applications such as wearable and mobile devices, personal medical appliances, and systems on chips.
