In Figure 1, the 5V linear regulator (U1) delivers as much as 150mA of load current when operating by itself. Operating with the external pass transistor shown (Q1), the circuit maintains 5V ...

Automobiles are the major means of transportation, which makes them a high demand on the market. Inside these automotive vehicles is a very complicated circuitry that tends to use quite an amount of ...

The AL8400 linear LED driver controller from Diodes Incorporated has been designed to tightly regulate a wide variation of high brightness LED currents via an external transistor. The AL8400 linear ...

The schematic shows an external pass transistor that can double the current output of a 5V linear regulator. The transistor increases the load current by creating another path from input to output. To ...
