GENERAL DESCRIPTION
The LT3041 is a high-performance, low-dropout linear regulator
featuring Analog Devices, Inc., ultra-low noise and ultra-high power
supply rejection ratio (PSRR) architecture for powering noise-sensitive
applications. Designed as a precision-current reference followed
by a high-performance voltage buffer, the LT3041 can be
easily paralleled to further reduce noise, increase output current,
and spread heat on the printed circuit board (PCB).
The LT3041 supplies 1 A at a typical 310 mV dropout voltage. The
operating quiescent current is nominally 4.3 mA and drops to 18
μA in shutdown. The wide output voltage range (0.2 V to 15 V)
of the LT3041 maintained by the unity-gain operation provides virtually
constant output noise, PSRR, bandwidth, and load regulation,
independent of the programmed output voltage. Additionally, the
regulator features VIOC, 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 LT3041 is available in a thermally enhanced,
14-lead 4 mm × 3 mm, DFN package.
