The TPS77133DGK from Texas Instruments is a highly efficient, low-dropout (LDO) voltage regulator designed to deliver a fixed output of 3.3V. This regulator is part of the TPS771xx family of linear regulators that offer the benefits of low dropout voltage, low-power operation, and miniaturized packaging. It is an excellent choice for battery-powered applications due to its ultra-low quiescent current and high accuracy.

Key Features

• Output Voltage: Precisely regulated 3.3V output, making it suitable for powering a wide range of low-voltage ICs.
• Dropout Voltage: Low dropout voltage of typically 28mV at 150mA load, allowing for efficient operation even when the input voltage is close to the output voltage.
• Load Current: Capable of delivering up to 150mA of continuous output current, sufficient for small to medium power needs.
• Quiescent Current: Ultra-low quiescent current of 28µA (typical) at no load, which is ideal for battery-powered devices where power conservation is crucial.
• Package: Available in an 8-pin MSOP (DGK) package, providing a compact footprint for space-constrained applications.
• Thermal Protection: Integrated thermal shutdown protection ensures the device operates within safe temperature limits.
• Stability: Stable with low-ESR capacitors, giving designers flexibility in choosing output capacitors.
