LT3097ADJCPBF规格书详情
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

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
