Key Features
- High Accuracy Output Voltage: The output voltage is accurate within ±2% for both 5.0 V and 3.3 V versions.
- Low Quiescent Current: The regulator draws only 90 µA of quiescent current in the ON mode and less than 1.0 µA in the OFF mode.
- Early Warning and Reset: Features an adjustable reset output and system monitor to provide early warning signals to the microprocessor.
- Fault Protection: Includes protection against over temperature, reverse polarity, short circuit, and thermal overload.
- Wide Temperature Range: Operates over a wide temperature range of -40°C to 150°C.
- Inhibit Function: Available on the 14-lead part, allowing the regulator to turn off and consume less than 1.0 µA of quiescent current.
- Pb-Free Devices: Compliant with lead-free requirements.
Applications
