The LM317 acts as a current regulator, It is connected to the battery through a one-way diode D1,limiting resistorR1, and a bias resistor R2. The D1 prevents the circuit from battery discharging when the power is out from this circuit. As the battery charges, the voltage across A poi...
LM317M can be used as a precision current regulator. Features • Output Current in Excess of 500 mA • Output Adjustable between 1.2 V and 37 V • Internal Thermal Overload Protection • Internal Short Circuit Current Limiting • Output Transistor Safe−Area Compensation • Floating ...
6. Power dissipation within an IC voltage regulator produces a temperature gradient on the die, affecting individual IC components on the die. These effects can be minimized by proper integrated circuit design and layout techniques. Thermal Regulation is the effect of these temperature gradients on ...
