    摘要: An apparatus includes a blocking N-channel MOS (LDMOS) transistor that prevents current flow when the supply connection is reversed. When connected properly, the body diode conducts to provide a start-up function. A bias generator is employed to enable the low drop-out voltage function, allowing the output voltage to be very close to supply.

    摘要: A system and method for driving a load at a desired operating level. A driver is connected to a load. The load can be selected from a plurality of loads by a selection system, such as a multiplexer, or a single load can be utilized. Feedback from the load is provided to the driver for achieving the desired operating level. A zero temperature coefficient resistance formed by two resistors having different resistances can be used so that the driver emulates an ideal resistor having a substantially zero temperature coefficient, providing a temperature independent current to the load.
