A short-protected buffer circuit comprising a source current output transistor (T1, Fig. 3) and a sink current output transistor (T2) is capable of providing high output current at low output voltage. A current-limiting bypass circuit, comprising two serious-connected field effect transistors (T3 and T4) and a voltage reference (T5 and T6), limits the gate voltage on the source current output transistor (T1) and thus limits the output source current. The circuit is compact and can be implemented in integrated circuit form. The output voltage at which protection starts is independent of temperature and of process variations. |
