TPS7A3001 Negative, High Voltage Linear Regulator



Texas Instruments'  -36V, 15.1µVRMS, 72dB PSRR, ultra-low noise negative linear regulator

Texas Instruments TPS7A3001 Negative, High Voltage, Ultra low Noise Linear Regulator Texas Instruments' TPS7A3001 is a negative, high-voltage (-36V), ultra-low noise (15.1µVRMS, 72dB PSRR) linear regulator capable of sourcing a maximum load of 200mA. This linear regulator includes a CMOS logic-level-compatible enable pin and capacitor-programmable soft-start function that allows for customized power-management schemes. Other features include built-in current limit and thermal shutdown protection to safeguard the device and system during fault conditions. The TPS7A30xx family is designed using bipolar technology and is ideal for high-accuracy, high-precision instrumentation applications where clean voltage rails are critical to maximize system performance. In addition, the TPS7A3001 is suitable for post DC/DC converter regulation. By filtering out the output voltage ripple inherent to DC/DC switching conversion, maximum system performance is provided in sensitive instrumentation, test and measurement, audio, and RF applications.   TPS7A3001 Datasheet
