Description
The CU253 is a 50mA fixed-output voltage regulator in the LD2980 series. It is suitable for low noise and low power applications, particularly in battery powered systems. The CU253 features a low dropout voltage and ultra-low quiescent current.
Specifications and features
- Stable with low ESR ceramic capacitors
- Ultra low dropout voltage (0.12V typ. at 50mA load, 7mV typ. at 1mA load)
- Very low quiescent current (80µA typ. at no load in ON mode; max 1µA in OFF mode)
- Guaranteed output current up to 50mA
- Logic-controlled electronic shutdown
- Output voltage options: 1.5V, 1.8V, 2.5V, 2.85V, 3.0V, 3.2V, 3.3V, 3.6V, 3.8V, 4.0V, 4.7V, 4.85V, 5.0V
- Internal current and thermal limit
- ± 0.5% 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
