The TPS77618QPWPREP is a high-performance, low-dropout (LDO) voltage regulator fabricated by Texas Instruments, a leader in semiconductor solutions. This device is specifically designed to deliver a stable and reliable power supply in a variety of electronic applications, particularly those that require a high degree of precision and operational stability under varying conditions.

Key Features

  • Output Voltage: The TPS77618QPWPREP provides a fixed output voltage of 1.8V, which is ideal for powering sensitive digital circuits that require a stable low-voltage supply.
  • High Accuracy: This regulator offers excellent regulation with a tight output accuracy, ensuring that the voltage remains consistent even with changes in input voltage or load conditions.
  • Dropout Voltage: The LDO features a low dropout voltage, which enables it to continue providing a regulated output even when the input voltage is very close to the output voltage, thus improving efficiency and battery life in portable applications.
  • Current Capacity: Capable of supplying up to 500mA of output current, the TPS77618QPWPREP can power a range of components from microprocessors to peripheral devices.
  • Thermal and Overcurrent Protection: The device includes built-in thermal shutdown and overcurrent protection features to safeguard the regulator and downstream components from potential damage due to excessive heat or current.
  • Package: It comes in a thermally enhanced 20-pin TSSOP (Thin Shrink Small Outline Package) that provides a compact footprint and excellent thermal performance.


The versatility of the TPS77618QPWPREP makes it suitable for a broad range of applications, including:

  • Battery-powered devices
  • Portable and handheld equipment
  • Microcontrollers and digital systems
  • Telecommunications infrastructure
  • Automotive electronics
  • Industrial control systems
