LT3065 Series
45V V
IN
, 500mA Low Noise,
Linear Regulator with Programmable
Current Limit and Power Good
DESCRIPTION
The
LT
®
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.
