Product Overview: TPS79625 Voltage Regulator from Texas Instruments
The TPS79625 is a high-performance, low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver a stable and precise 2.5V output voltage. This regulator is a part of the TPS796xx family, which is known for its ultra-low noise performance and high power supply rejection ratio (PSRR), making it an ideal choice for sensitive RF and analog circuitry that requires a clean power supply.
With a dropout voltage of just 85mV at full load, the TPS79625 ensures efficient operation even when the input voltage is close to the output voltage. This feature is particularly beneficial in battery-powered applications where maximizing the usage of the available voltage range is crucial for extending battery life.
The TPS79625 can supply up to 1A of output current, which is suitable for a variety of applications, including portable devices, wireless communication equipment, and digital electronics. Additionally, the device incorporates several safety features such as thermal shutdown and overcurrent protection, which safeguard the regulator and the load from damage due to abnormal operating conditions.
One of the key advantages of the TPS79625 is its low noise performance, with a typical output voltage noise of 28µV RMS. This is particularly important for powering noise-sensitive components such as precision analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and voltage-controlled oscillators (VCOs).
The regulator is also highly versatile, with the ability to be configured in various ways. For instance, it supports adjustable output voltage versions through the use of external resistors. Moreover, the TPS79625 features enable pin functionality, allowing the device to be turned on or off as needed, which helps in reducing power consumption when the device is not in use.
The TPS79625 comes in a variety of package options, including the small outline integrated circuit (SOIC) and the thin shrink small outline package (TSSOP), providing flexibility for different design requirements and space constraints.
Overall, the TPS79625 from Texas Instruments stands out as a reliable and efficient voltage regulator, perfect for applications that demand high accuracy, low noise, and robust protection features.
