FEATURES

LT3065 Series

45V V

, 500mA Low Noise,

Linear Regulator with Programmable

Current Limit and Power Good

DESCRIPTION

The

3065 Series

are micropower, low noise, low dropout

voltage (LDO) linear regulators that operate over a 1.6V

to 45V input voltage range. The devices supply 500mA 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.

A single external resistor programs the LT3065’s current

limit, accurate to ±10% over a wide input voltage and tem-

perature range. A PWRGD flag indicates output regulation.

The LT3065 optimizes stability and transient response

with low ESR ceramic capacitors, requiring a minimum of

3.3µF. Internal protection circuitry includes current limiting

with foldback, thermal limiting, reverse battery protection,

reverse current protection and reverse output protection.

The LT3065 is available in fixed output voltages of 1.2V,

1.5V, 1.8V, 2.5V, 3.3V, and 5V, and as an adjustable de-

vice with an output voltage range from 0.6V to 40V. The

LT3065 is available in the thermally-enhanced 10-lead

3mm × 3mm DFN and 12-lead MSOP packages.
