The TPS79333DBVR from Texas Instruments is a low dropout (LDO) 3.3V voltage regulator with a 200mA maximum current capability and high power supply rejection ratio (PSRR) of 75dB. It features an operating temperature range from -40°C to 125°C and a specification for line regulation of 0.005%. It also has low dropout voltage of 250mV at 200mA load current, and fast transient response of 70uS. In addition to its low power consumption of 40uA, it also includes internal protection against over-voltage, over temperature, and current limit. The TPS79333DBVR is designed for a wide range of applications, including industrial, telecommunications, computing, automotive, medical, and other general-purpose products.
