WebLM317. These regulators use an NPN Darlington pass transistor (Figure 1), and are often referred to as NPN regulators. The demand for higher performance is being met by the newer low-dropout (LDO) regulators. THE NPN REGULATOR The NPN Darlington pass transistor configuration requires that at least 1.5V to 2.5V be maintained from input-to … WebTrue, an NMOS enters triode under that condition, for a PMOS the reverse is true! With this simple circuit, you can see than when V.in is low the collector of Q.1 will float, causing it to rise to V.supply due to the pull-up (which is large to limit current). The gate of M1 willbe high, and the circuit will be non-conducting.
