The LT3045-EP is a high performance low dropout linear
regulator featuring LTC’s ultralow noise and ultrahigh PSRR
architecture for powering noise sensitive applications.
Designed as a precision current reference followed by a
high performance voltage buffer, the LT3045-EP can be
easily paralleled to further reduce noise, increase output
current and spread heat on the PCB.
The device supplies 500mA at a typical 260mV dropout
voltage. Operating quiescent current is nominally 2.2mA
and drops to <<1μA in shutdown. The LT3045-EP’s wide
output voltage range (0V to 15V) while maintaining unitygain 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.
The LT3045-EP is stable with a minimum 10μF ceramic
output capacitor. Built-in protection includes reversebattery protection, reverse-current protection, internal
current limit with foldback and thermal limit with hysteresis.
The LT3045-EP is available in thermally enhanced 12-
Lead MSOP package. Additional application and technical
information can be found in LT3045 data sheet.
