The TPS79318YEQT from Texas Instruments is a high-performance, ultra-low noise, low-dropout linear voltage regulator designed to deliver a fixed output voltage of 1.8V. This regulator is ideal for applications requiring a low noise power supply, such as RF and analog circuits, with the added benefit of a low dropout voltage that enhances efficiency by allowing operations closer to the battery voltage.

Key Features

• Output Voltage: 1.8V fixed output with high accuracy.
• Load Current: Capable of supplying up to 200mA of output current.
• Dropout Voltage: Ultra-low dropout performance, typically 17mV at 200mA, allows for efficient use of power.
• Noise Performance: Exceptionally low noise output, typically 32µVRMS, suitable for sensitive RF and analog circuitry.
• Stability: Stable with low ESR ceramic capacitors, reducing the size and cost of external components.
• Power-Saving Modes: Features a high-efficiency EN (enable) pin that can be used to switch the regulator on and off.
• Thermal Protection: Built-in thermal shutdown and overcurrent protection to safeguard the device and the load.
