This Product Selection Guide contains information to help select products in the Voltage Regulators - Linear Regulator Controllers category on DigiKey.com
Linear voltage regulation refers to the use of a pass element (usually a bipolar or field effect transistor) connected in series with a load, together with appropriate control circuits driving the pass element so as to produce a nominally constant voltage across the load that is insensitive to changes in supply voltage to the circuit or the amount of load current drawn. Products within this family provide the necessary control function for use with an external pass element, distinguishing them from integrated linear regulators which combine a pass element with control circuits in a single device package.
SelectionCharacteristics
Type: Indicates the style and configuration of the device.
Number of Outputs: Indicates how many outputs this device provides.
Current - Supply: Typically this rating indicates the nominal amount of current you would expect the device to draw during normal operation.
Voltage - Input: Typically represented by a range, this indicates the low and high voltage limits which one can expect standard operation. Voltages outside this range may damage the device and other system components.
Operating Temperature: Recommended operating temperature, typically given in a range or as a maximum. Exceeding these temperatures may affect performance or damage the device and other system components.
Supplier Device Package: This is what the manufacturer calls the package of this device. They are manufacturer specific. It is typically best to use the actual dimensions from the datasheets rather than to go by this terminology when designing your circuit.
Package / Case: Indicates the type of protective case used on an electronic component to allow easy handling, installation, and protection. This selection was determined to be the closest industry standard applicable to the supplier device packaging. Typically it is best to check the actual dimensions from the datasheet rather than depend on this terminology when designing your circuit.
