DESCRIPTION
The
LT
®
3095
generates two low noise bias supplies from
a common input voltage ranging from 3V to 20V. Each
channel includes a fixed frequency, peak current-mode
step-up switching regulator and a low noise, single-
resistor-programmable 50mA linear regulator. The linear
regulator’s high power supply ripple rejection (PSRR)
combined with its low noise performance results in less
than 100µV
P-P
output ripple and noise.
Each boost regulator adjusts its output voltage to 2V above
the corresponding linear regulator’s output voltage, opti-
mizing power dissipation, PSRR and transient response.
This tracking scheme, along with internal boost regulator
frequency compensation and integrated Schottky diodes,
minimizes external component count and simplifies system
design. Each linear regulator includes internal current limit
and thermal limit protection circuitry.
The LT3095 switching frequency is externally program-
mable with a single resistor from 450kHz to 2MHz. A
SYNC pin allows synchronization to an external clock. The
LT3095 is available in a thermally enhanced, low profile
(0.75mm) 24-lead 3mm × 5mm QFN package.
