TPS7A33 High PSRR Power Supply

TPS7A33, TPS7A47 ultra-low noise, high PSRR (+-5V) power supply can be transplanted to the system with precision, low noise, high PSRR requirements to provide power, suitable for powering bipolar amplifiers, data converters or other noise-sensitive analog circuits. The chips used are: TPS84259, TPS 84250, TPS7A33 and TPS7A47. This design is suitable for high-accuracy, high-precision measurement instrument applications. In such applications, in order to obtain maximum system performance, a regular voltage rail is critical. This ultra-low noise, high PSRR (+-5V) power supply is very suitable for powering operational amplifiers, analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and other high-performance analog circuits. Positive and negative voltages can be output from a 12V/24V power supply. By changing the resistor, the output voltage can be adjusted from +/-3V to +/-15V. It can output 1A current.
