GENERAL DESCRIPTION
The LT3046 is a high-performance, low-dropout linear
regulator featuring Analog Devices, Inc. ultra-low noise
and ultra-high PSRR architecture for powering noisesensitive
applications. Designed as a precision current
reference followed by a high-performance voltage
buffer, the LT3046 can be easily paralleled to further
reduce noise, increase output current, and spread heat
on the PCB.
The device supplies 200mA at a typical 300mV dropout
voltage. Operating quiescent current is nominally
3.7mA and drops to 26μA in shutdown. The LT3046’s
wide output-voltage range (0.2V to 19V) while
maintaining unity-gain operation provides virtually
constant output noise, PSRR, bandwidth, and load
regulation, independent of the programmed output
voltage. Additionally, the regulator features
programmable current limit, fast start-up capability,
and programmable power good to indicate output
voltage regulation.
Built-in protection includes reverse-battery protection,
reverse-current protection, internal current limit with
foldback and thermal limit with hysteresis. The LT3046
is available in a thermally enhanced, 12-lead, 3mm ×
3mm, DFN package.
