LT3097ADJC#PBF

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 architecture for powering noise-sensitive applications. Each regulator delivers up to 500mA with a typical 260mV/235mV dropout voltage. Operating quiescent current is nominally 2.2mA/2.35mA and drops to 0.3µA/3µA in shutdown. This has a wide output voltage range error amplifier that operates in unity-gain and provides virtually constant output noise, PSRR, bandwidth and load regulation, independent of the programmed output voltage. Application includes bipolar very low-noise power supplies, RF power supplies: phase-locked loops, voltage-controlled oscillators, mixers, low-noise amplifiers, and power amplifiers, low-noise instrumentation, high-speed and high-precision data converters, medical applications: imaging and diagnostics, precision power supplies, post regulator for switching supplies.

• Single capacitor per channel improves noise and PSRR
• Single resistor per channel programs output voltage, programmable current limit
• Programmable power good, fast start-up capability
• Precision enable/undervoltage lockout (UVLO), internal current limit with foldback
• Wide input voltage range from ±1.8V to ±20V
• Ultra-high PSRR is 76dB (positive) and 74dB (negative) at 1MHz
• SET pin current is 100µA, ±1% initial accuracy
• Low-dropout voltage is 260mV (positive) and 235mV (negative)
• Output voltage range from 0V to 15V (positive) and 0V to -19.5V (negative)
• 22 lead plastic DFN package, temperature range from -40°C to +125°C
