LT3045-1  
20V, 500mA, Ultralow Noise,  
Ultrahigh PSRR Linear Regulator with VIOC Control  
FEATURES  
DESCRIPTION  
n
Ultralow RMS Noise: 0.8µV  
(10Hz to 100kHz)  
The LT®3045-1 is a high performance low dropout linear  
regulatorfeaturingLTC’sultralownoiseandultrahighPSRR  
architectureforpoweringnoisesensitiveapplications.De-  
signed as a precision current reference followed by a high  
performance voltage buffer, the LT3045-1 can be easily  
paralleled to further reduce noise, increase output current  
and spread heat on the PCB. In addition to the LT3045  
feature set, the LT3045-1 incorporates a VIOC tracking  
function to control an upstream switching converter to  
maintain a constant voltage across the LT3045-1 and  
hence minimize power dissipation.

Single Resistor Programs Output Voltage  
Programmable Current Limit  
Low Dropout Voltage: 260mV  
The device supplies 500mA at a typical 260mV dropout  
voltage. Operating quiescent current is nominally 2.3mA  
and drops to <<1µA in shutdown. The LT3045-1’s wide  
output voltage range (0V to 15V) 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 capa-  
bility and programmable power good to indicate output  
voltage regulation.  
Output Voltage Range: 0V to 15V  
Programmable Power Good  
Fast Start-Up Capability  
Precision Enable/UVLO  
Parallelable for Lower Noise and Higher Current  
Internal Current Limit with Foldback  
Minimum Output Capacitor: 10µF Ceramic  
Reverse-Battery and Reverse-Current Protection  
12-Lead MSOP and 3mm × 3mm DFN Packages  
The LT3045-1 is stable with a minimum 10µF ceramic  
output capacitor. Built-in protection includes reverse-  
battery protection, reverse-current protection, internal  
currentlimitwithfoldbackandthermallimitwithhysteresis.  
The LT3045-1 is available in thermally enhanced 12-Lead  
MSOP and 3mm × 3mm DFN packages.
