The LT1185 uses a saturation-limited NPN transistor as
the pass element. This device gives the linear dropout
characteristics of a FET pass element with significantly
less die area. High efficiency is maintained by using special
anti-saturation circuitry that adjusts base drive to track
load current. The “on resistance” is typically 0.25
.
Accurate current limit is programmed with a single 1/8W
external resistor, with a range of zero to three amperes. A
second, fixed internal limit circuit prevents destructive
currents if the programming current is accidentally over-
ranged. Shutdown of the regulator output is guaranteed
when the program current is less than 1
μ
A, allowing
external logic control of output voltage.
The LT1185 has all the protection features of previous
LTC regulators, including power limiting and thermal
shutdown.

The LT
1185 is a 3A low dropout regulator with adjustable
current limit and remote sense capability. It can be used as
a positive output regulator with floating input or as a
standard negative regulator with grounded input. The
output voltage range is 2.5V to 25V, with
±
1% accuracy on
the internal reference voltage.
