GENERAL DESCRIPTION

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.

FEATURES

? Ultra-low output RMS noise: 0.8 μV rms (10 Hz to 100 kHz)

? Ultra-low output noise spectral density: 2 nV/√Hz (Positive) and

2.2 nV/√Hz (Negative) at 10 kHz

? Ultra-low 1/f noise: 10 μV p-p (Positive) and 3.2 μV p-p (Negative)

(0.1 Hz to 10 Hz)

? Ultra-high PSRR: 76 dB (Positive) and 74 dB (Negative) at 1

MHz

? Output current: 500 mA

? Wide input voltage range: ±1.8 V to ±20 V

? Single capacitor per channel improves noise and PSRR

? SET pin current: 100 μA, ±1 initial accuracy

? Single resistor per channel programs output voltage

? Programmable current limit

? Low-dropout voltage: 260 mV (Positive) and 235 mV (Negative)

? Output voltage range: 0 V to 15 V (Positive) and 0 V to –19.5 V

(Negative)

? Programmable power good

? Fast start-up capability

? Precision enable/undervoltage lockout (UVLO)

? Internal current limit with foldback

? Minimum output capacitor: 10 μF ceramic

? Compact, low-profile, 22-lead, 6 mm × 3 mm, Plastic DFN package

APPLICATIONS

? 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

? Postregulator for switching supplies
