Short-circuit protection for regulators. It is not always realized that, when a short-circuit occurs in a circuit supplied via a Type 78xx regulator, this and similar types of regulator can not ...

There are many circuits for low voltage regulators. For higher voltages, such as supplies for valve circuits, the situation is different. That’s why we. ... One Reply to “High-Voltage Regulator With ...

Transistor VT2 provides short-circuit protection to the load, with red LED D4 indicting an overload. (D2 blows out simultaneously with an overload.) Short-circuit current does not exceed 38 mA.

To address the issue of excessive current in the power transistor during output short-circuit conditions in conventional overcurrent protection circuits for low dropout regulators (LDOs), this paper ...

Figure 2 Three parts comprise a circuit for linear regulator programming with PWM. ... This capacitance ratio also provides protection for U1’s Vsense input, since it ensures that even a sudden short ...

Additionally a safe operating area protection is added to both regulators. Let’s look at the positive regulator. The ... risk of damage to the output stage in case there’s an overload condition or ...

The R-78 series is a linear regulator that offers savings in energy, board space, and cost, ... The R-78K series features various protection features including under-voltage lockout and short-circuit ...

The actual regulator consists of just three transistors. A fourth has been added for the current limiting function. The circuit is a positive series regulator, using a pnp transistor (T2) to keep the ...
