The L9777 is a monolithic integrated low drop regulator which can supply up to 200 mA, available in the PowerSSO-12 package.
It is designed to supply microprocessor systems under severe conditions of automotive applications and therefore equipped with additional protection functions against over load, short circuit and over temperature.
Of course the L9777 can also be used in other applications where a regulated voltage is required.Key Features
- Operating DC supply voltage range 5.6 V to 31 V
- Low current consumption (110 μA typ @ Iout= 0)
- High precision output voltage (2 %)
- Low dropout voltage
- VDD tracking regulator switchable on/off by VDD_EN pin
- Reset circuit sensing the output voltage down to 1 V.
- Double reset function
- Adjustable reset threshold
- External capacitor to set NMI/ reset power up delay and watchdog frequency
- Over temperature protection
- Wide temperature range (TJ= -40 °C to 150 °C)
- Short circuit proof
