Data Sheet LT3074
5.5V, 3A Ultralow Noise, High PSRR, 45mV Dropout Linear Regulator with PMBus FEATURES GENERAL DESCRIPTION  Ultralow RMS Noise: 1.2µVRMS (10Hz to 100kHz)
 Ultralow Spot Noise: 3.5nV/√Hz at 10kHz The LT3074 is a low voltage, ultralow noise, and ultrafast
transient response linear regulator with a PMBus serial
interface. The device supplies up to 3A with a typical
dropout voltage of 45mV. A 4.7µF reference bypass
capacitor decreases output voltage noise to 1.2μVRMS.
The wide bandwidth and high PSRR permit the use of
small ceramic capacitors, saving bulk capacitance and
cost. The LT3074 is supported by the LTPowerPlay
software development tool with a graphical user
interface (GUI).  Ultralow 1/f Noise: 7µVP-P (0.1Hz to 10Hz)
 High PSRR at High Frequency: 52dB at 1MHz
 Ultrafast Transient Response
 Dropout Voltage: 45mV Typical
 100µA Reference Current: ±0.5% Initial Accuracy
 Precision Current Monitor: ±3% Accuracy at 3A
 PMBus Capability Includes:
 VOUT, IOUT, VIN, VBIAS, and Temperature Reporting
 VOUT Margining
 IOUT Overcurrent and Undercurrent Warn Limits
 VOUT, VIN, and VBIAS Undervoltage and Overvoltage Warn Limits
