LT3061 Series 45V VIN, Micropower, Low Noise, 100mA LDO with Active Output Discharge
FEATURES DESCRIPTION
n
Input Voltage Range: 1.6V to 45V
The LT®3061 is a micropower, low dropout (LDO) linear n
Output Current: 100mA
regulator that operates over a 1.6V to 45V supply range n
Output Discharge
and is available in a series of fixed output and adjustable n
Quiescent Current: 45µA
versions. The device supplies 100mA of output current n
Dropout Voltage: 250mV
with a typical dropout voltage of 250mV. A single external n
Low Noise: 30µVRMS (10Hz to 100kHz)
capacitor provides programmable low noise reference n
Adjustable Output (VREF = 600mV)
performance and output soft-start functionality. The n
Fixed Output Voltages: 3.3V, 5V
LT3061’s quiescent current is merely 45μA and provides n Output Tolerance: ±2% Over Load, Line, and fast transient response with a minimum 3.3μF output ca- Temperature pacitor. In shutdown, quiescent current is less than 3μA n Single Capacitor Soft-Starts Reference and Lowers and the reference soft start capacitor is reset. Output Noise The LT3061 features an NMOS pull-down that discharges n Shutdown Current: < 3µA the output when SHDN or IN is driven low. n Reverse Battery Protection n Current Limit Foldback and Thermal Limit Protection Internal protection circuitry includes reverse-battery n 8-Lead 2mm × 3mm DFN and MSOP Packages protection, reverse-current protection, current limit with foldback and thermal shutdown.
APPLICATIONS
The LT3061 is available in fixed output voltages of 3.3V n Battery Powered Systems and 5V, and as an adjustable device with an output voltage n Automotive Power Supplies range from the 600mV reference up to 19V. The LT3061 n Industrial Power Supplies is offered in the thermally enhanced 8-lead 2mm × 3mm n Avionic Power Supplies DFN and MSOP packages. n Portable Instruments All registered trademarks and trademarks are the property of their respective owners.
