The TPS75825KTTR is a low quiescent current linear voltage regulator with a programmable output voltage. It is able to provide a constant, regulated output voltage over a wide range of input voltages, making it suitable for applications such as system power supplies and embedded systems. Its uses include powering portable electronics and other applications requiring accurate voltage regulation. Additionally, the TPS75825KTTR provides an additional control loop that helps reduce output voltage noise.

The TPS75825KTTR provides a comprehensive feature set that allows it to meet a variety of voltage regulation needs. It achieves high accuracy (1.25V) and low dropout when used in either current limiting or fixed-output programming mode. Its low quiescent current (typically 75μA typ.) ensures minimal power loss in mobile applications, while its 125mV minimum dropout voltage provides excellent load regulation under light load conditions. Besides its low dropout voltage performance, the TPS75825KTTR offers fast transient response and excellent line and load transient performance for stable voltage regulation. The TPS75825KTTR also features an enable pin that allows the device to operate in standby mode for minimal current consumption when needed.

The TPS75825KTTR uses a programmable output voltage to provide accurate voltage regulation for a wide range of applications. The voltage can be programmed from 0.8V to 5.5V using an external resistor divider network. The output voltage is then regulated in response to changes in input voltage, with the output voltage remaining constant within ±1%. This precision is maintained over a wide range of line, load, and temperature conditions, making the TPS75825KTTR suitable for applications such as system power supplies, embedded systems, and other applications requiring accurate voltage regulation.

The TPS75825KTTR also features a control loop that helps reduce output voltage noise. The control loop consists of an external capacitor, connected to the output of the device. The output voltage is monitored by the control loop, and when the voltage starts to drift off nominal, the control loop reduces the size of the output capacitor to reduce the output impedance and thus reduce noise. This feature helps the TPS75825KTTR maintain the desired output voltage accuracy over a wide range of line, load and temperature conditions.

The TPS75825KTTR is offered in a small SOT-23-6 package and is available with thermal protection and reverse current protection. For applications such as portable electronics, the TPS75825KTTR delivers high accuracy, low quiescent current and excellent line and load transient performance. Its wide input/output voltage range, low dropout voltage, enable pin, and control loop make the TPS75825KTTR ideal for many voltage regulation applications.
