LT1185CT is a voltage regulator IC (integrated circuit) manufactured by Linear Technology (now part of Analog Devices). It is a 3A low dropout positive adjustable regulator, meaning that it can regulate a voltage to a precise level, even when the input voltage is only slightly higher than the desired output voltage.
Features
- Output voltage adjustable from 1.2V to 30V
- Low dropout voltage (1.2V typical)
- Output current up to 3A
- Thermal overload protection
- Short circuit protection
- Adjustable current limit
- Wide input voltage range (up to 40V)
Application
- Power supply for microprocessors, DSPs, and other digital circuits
- Power supply for audio and video equipment
- Power supply for instrumentation and test equipment
- Battery charger circuits
- Voltage regulator for automotive applications
