LT3062 Series 45V VIN, Micropower, Low Noise, 200mA LDO
FeaTures DescripTion
n
Input Voltage Range: 1.6V to 45V
The LT®3062 is a micropower, low dropout (LDO) linear n
Output Current: 200mA
regulator that operates over a 1.6V to 45V supply range n
Quiescent Current: 45µA
and is available in a series of fixed output and adjustable n
Dropout Voltage: 300mV
versions. The device supplies 200mA of output current n
Low Noise: 30µVRMS (10Hz to 100kHz)
with a typical dropout voltage of 300mV. A single external n
Adjustable Output (VREF = 600mV)
capacitor provides programmable low noise reference n Fixed Output Voltages: 3.3V, 5V performance and output soft-start functionality. The n Output Tolerance: ±2% Over Load, Line, and LT3062’s quiescent current is merely 45μA and provides Temperature fast transient response with a minimum 3.3μF output n Single Capacitor Soft-Starts Reference and Lowers capacitor. In shutdown, quiescent current is less than 1μA Output Noise and the reference soft start capacitor is reset. n Shutdown Current: < 1µA The LT3062 optimizes stability and transient response n Reverse Battery Protection with low ESR, ceramic output capacitors. The LT3062 n Current Limit Foldback and Thermal Limit Protection does not require the addition of ESR as is common with n 8-Lead 2mm × 3mm DFN and MSOP Packages other regulators. Internal protection circuitry includes reverse-battery pro-
