The circuit design of this dual polarity power supply is regulated with the use of a positive (78xx) and negative (79xx) voltage regulators. What is the purpose of dual power supply? Dual polarity ...
Dual-voltage power supply is required especially for powering the op-amps and some of the instrumentation amplifiers. A few low-power audio pre-amplifiers also use dual-voltage supply. This circuit ...
Among regulators, the simplest regulator circuit is for a low-dropout (LDO) voltage regulator whose topology is shown in Fig. 1. As a linear voltage regulator, its ...
