| Abstract: | Compensating pipe is a very important component of LDO regulator as output power device. This paper discusses and analyzes the current gain β, the collector max working current ICM and the saturation dropout voltage VCE（SAT） between LPNP and VPNP form the layout and the equivalent circuit, and at last the result is presented to understand the design of the compensating pipe of LDO. |
