The SPX3819 is a positive voltage regulator with a low dropout voltage and low noise output. In addition, this device offers a very low ground current of 800μA at 100mA output. The SPX3819 has an initial tolerance of less than 1% max and a logic compatible ON/OFF switched input. When disabled, power consumption drops to nearly zero.
- Low Noise: 40μV Possible
- High Accuracy: 1%
- Reverse Battery Protection
- Low Dropout: 340mV at Full Load
- Low Quiescent Current: 90μA
- Zero Off-Mode Current
- Fixed and Adjustable Output Voltages:
- 1.2V, 1.5V, 1.8V, 2.5V, 3.0V, 3.3V and 5.0V Fixed Output Voltages
- ≥1.235V Adjustable Output Voltages
- Portable Consumer Equipment
- Portable Instrumentation
- Industrial Equipment
- SMPS Post Regulators
Other key features include reverse battery protection, current limit, and thermal shutdown. The SPX3819 includes a reference bypass pin for optimal low noise output performance. With its very low output temperature coefficient, this device also makes a superior low power voltage reference.
The SPX3819 is an excellent choice for use in battery-powered applications such as cordless telephones, radio control systems, and portable computers. It is available in several fixed output voltage options or with an adjustable output voltage.
