The UC382 is a low-dropout linear regulator that provides a fast response to load changes, making it suitable for driving GTL and BTL buses.
Key features include:
- Fast transient response
- Low dropout voltage (450 mV maximum at 3-A load)
- Separate bias and VIN pins
- Available in fixed-output voltages (1.5 V, 2.1 V, 2.5 V) or adjustable output voltage
- 5-pin package allows Kelvin sensing of load voltage
- Reverse current protection and short circuit protection
Applications
The UC382 is easy to use and requires minimal external components. It is suitable for a wide range of applications, including Ultra-Fast GTL or BTL applications.
Decoupling and Capacitor Selection
Decoupling capacitors are required on the input and output, and local decoupling is recommended if the UC382 is far from the power supply. The output should be decoupled with at least 100 LF of high-quality tantalum or Sanyo OSCON capacitors.
