LT1185

Low Dropout Regulator

FEATURES

■

Low Resistance Pass Transistor: 0.25

Ω

Dropout Voltage: 0.75V at 3A

1% Reference Voltage

Accurate Programmable Current Limit

Shutdown Capability

Internal Reference Available

Full Remote Sense

Low Quiescent Current: 2.5mA

Good High Frequency Ripple Rejection

Available in 5-Lead TO-220 and DD Packages

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 0.25Ω.

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 1µA, allowing

external logic control of output voltage.

The LT1185 has all the protection features of previous

LTC regulators, including power limiting and thermal

shutdown.

DESCRIPTIO

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.
