TPS70158PWPR

TPS70158PWPR is a high-performance, low-noise, low-dropout linear regulator, belonging to PMIC - Voltage Regulators - Linear (PMIC-VRL). It is a single-chip integrated solution for voltage control with a wide range of applications. TPS70158PWPR is optimized for mobile computing and embedded designs. It has the advantages of high efficiency, high output current, low dropout voltage, low noise, wide temperature range, and low chip cost.

The key feature of the TPS70158PWPR is its low 0.11 Ω internal VSET resistance and short-circuit protection. This helps reduce power losses and increase efficiency. This makes it one of the top performing linear regulators in the PMIC-VRL market. With its wide 4.5V to 10V adjustable output range and high 2A output current capability, the TPS70158PWPR is an ideal solution for powering microprocessors and other mobile applications.

The working principle of TPS70158PWPR is based on the linear regulator principle. It contains an N-channel low-side power MOSFET (metal-oxide semiconductor field-effect transistor), resistor and reference voltage inside. The N-channel MOSFET is controlled by two external resistors and a voltage reference to regulate the output voltage. The reference voltage is fixed and it never changes, which is used to compare with the voltage of the output. When the output voltage is higher than the reference voltage, the N-channel MOSFET is turned off, thus allowing current to flow through the output. When the output voltage is lower than the reference voltage, the N-channel MOSFET is turned on and acts as a high impedance connection, preventing current from flowing through the output.
