Abstract
A power management system for a laser range finder including a microcontroller which controls the supply of power by a series of linear regulators to analog electronics and digital electronics such that the respective electronics units are powered only during intervals when they require power during operation of the laser range finder. The linear regulators and a laser firing pulse generator circuit are powered by simplified DC/DC converter circuitry which is, in turn, supplied with power by a solid state front end circuit subject to control by the microcontroller and which includes first, second, and third transistors providing reverse voltage protection, overvoltage protection, and reduced power consumption.
