Description
General part information
LT3097 Series
The LT3097 is a dual, positive and negative, high-performance, low-dropout linear regulator featuring Analog Devices, Inc., ultralow noise and ultra-high power supply rejection ratio (PSRR) architecture for powering noise-sensitive applications. Each regulator delivers up to 500 mA with a typical 260 mV/235 mV (positive/negative) dropout voltage.Operating quiescent current is nominally 2.2 mA/2.35 mA (positive/negative) and drops to 0.3 μA/3 μA (positive/negative) in shutdown. The LT3097 has a wide output voltage range (0 V to 15 V, positive and 0 V to -19.5 V, negative) error amplifier that operates in unity-gain and provides virtually constant output noise, PSRR, bandwidth and load regulation, independent of the programmed output voltage.LT3097 is stable with a minimum 10 μF ceramic output capacitor for each channel. Built-in protection includes internal current limit with foldback and thermal limit with hysteresis. The positive regulator also includes reverse-battery protection and reverse-current protection. The LT3097 is available in a thermally enhanced, 22-lead 6 mm × 3 mm, Plastic dual-flat no-leads (DFN) package.APPLICATIONSBipolar very low-noise power suppliesRF power supplies: phase-locked loops, voltage-controlled oscillators, mixers, low-noise amplifiers, and power amplifiersLow-noise instrumentationHigh-speed and high-precision data convertersMedical applications: imaging and diagnosticsPrecision power suppliesPostregulator for switching supplies
