The TPS77118DGKRG4 is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver a continuous 150 mA output with an ultra-low dropout of just 28mV at full load. This advanced power management integrated circuit (IC) is ideal for battery-powered and low-power applications where power efficiency is paramount.

Key Features

• Output Voltage: The device provides a fixed output voltage of 1.8V, which is suitable for powering sensitive electronic components that require stable voltage levels for optimal performance.
• High Accuracy: The output voltage tolerance is tightly regulated to within ±1.5% over the entire range of input voltage, output load, and temperature, ensuring reliable operation under varying conditions.
• Low Dropout: With an ultra-low dropout voltage, the TPS77118DGKRG4 can maintain output regulation with a minimal difference between the input and output voltages, making it highly efficient for use in systems with tight voltage margins.
• Low Quiescent Current: The device features a low quiescent current of only 92µA (typical), which is reduced to 1µA in shutdown mode, thereby extending battery life in portable applications.
• Fast Transient Response: The regulator is designed to provide excellent transient response, which helps maintain a stable output voltage despite rapid changes in load, such as when powering up digital processors or memory.
• Thermal Protection: Built-in thermal shutdown protection ensures that the device operates within safe temperature limits, preventing potential damage from overheating.
• Overcurrent Protection: The TPS77118DGKRG4 also incorporates overcurrent protection to safeguard the regulator and the load from excessive current draw.
