FeaTures

DescripTion

The LT^®3062 is a micropower, low dropout (LDO) linear

regulator that operates over a 1.6V to 45V supply range

and is available in a series of fixed output and adjustable

versions. The device supplies 200mA of output current

with a typical dropout voltage of 300mV. A single external

capacitor provides programmable low noise reference

performance and output soft-start functionality. The

LT3062’s quiescent current is merely 45μA and provides

fast transient response with a minimum 3.3μF output

capacitor. In shutdown, quiescent current is less than 1μA

and the reference soft start capacitor is reset.

Input Voltage Range: 1.6V to 45V

Output Current: 200mA

Quiescent Current: 45µA

Dropout Voltage: 300mV

Low Noise: 30µV

(10Hz to 100kHz)

Adjustable Output (V

= 600mV)

Fixed Output Voltages: 3.3V, 5V

Output Tolerance: 2ꢀ Over Load, Line, and

Temperature

Single Capacitor Soft-Starts Reference and Lowers

Output Noise

Shutdown Current: < 1µA

The LT3062 optimizes stability and transient response

with low ESR, ceramic output capacitors. The LT3062

does not require the addition of ESR as is common with

other regulators.

Automotive Power Supplies

The LT3062 is available in fixed output voltages of 3.3V

and 5V, and as an adjustable device with an output voltage

range from the 600mV reference up to 40V. The LT3062

is offered in the thermally enhanced 8-lead 2mm × 3mm

DFN and MSOP packages.
