TPS7A33 - Texas Instruments

TPS7A33 Ultralow-Noise Negative Voltage Regulator

The TPS7A33 series of linear regulators are negative voltage (–36 V), ultralow-noise (16-μVRMS, 72-dB PSRR) linear regulators capable of sourcing a maximum load of 1 A. The TPS7A33 series include a complementary metal oxide semiconductor (CMOS) logic-level-compatible enable pin (EN) to allow for user-customizable power management schemes. Other features avai.
