Features & Applications
The LD2981CU33TR is a low drop voltage regulator with an output voltage of 3.3 V and an output current up to 100 mA. It is available in surface mount SOT-89-3 package.
The low drop-voltage and the ultra low quiescent current make them suitable for low noise, low power applications and in battery powered systems.
Features:
- Stable with low ESR ceramic capacitors
- Ultra low dropout voltage
- Very low quiescent current
- Guaranteed output current up to 100mA
- Logic-controlled electronic shutdown
- Output voltage of 2.5; 3.0; 3.3; 5.0V
- Internal current and thermal limit
- ±0.75% tolerance output voltage available (A version)
- Output low noise voltage 160µVRMS
- Temperature range: -40 to 125°C
- Smallest package SOT23-5L and SOT-89
- Fast dynamic response to line and load changes
Applications:
- Cellular phone
- Palmtop/Laptop computer
- Personal Digital Assistant (PDA)
- Personal Stereo
- Camcorder and Camera
