Texas Instruments TPS7A4901 / TPS7A3001 Linear Regulators
The Texas Instruments TPS7A4901 is a positive, high-voltage (+36V), ultralow noise (15.4µVRMS, 72dB PSRR) linear regulator capable of sourcing a maximum load of 150mA. The TI TPS7A3001 is a negative, high-voltage (-36V), ultralow-noise (15.1µVRMS, 72dB PSRR) linear regulator capable of sourcing a maximum load of 200mA. These TI linear regulators include a CMOS logic-level compatible enable pin and capacitor-programmable soft-start function that allows for customized power-management schemes. Other features available include built-in current limit and thermal shutdown protection to safeguard the device and system during fault conditions. The TPS7A4901 and TPS7A3001 linear regulators are ideal for high-accuracy, high-precision instrumentation applications where clean voltage rails are critical to maximize system performance. The TI TPS7A30-49EVM-567 evaluation module is a fully assembled and tested circuit for evaluating the TPS7A3001 and TPS7A4901 low-dropout linear regulators in the DGN (3mm x 5mm MSOP-8) package.
