Method to limit the inrush current in large output capacitance LDOs |
摘要 |
The present document relates to a pre-charge circuit of electronic circuits having Miller compensation and significant output capacitance such as LDOs or multistage amplifiers. The pre-charge circuit limits an inrush current right after enabling of the electronic circuit. The pre-charge circuit limits and clamps the fast charging of the Miller capacitor. A delay circuit disables the pre-charge circuit when the bias conditions of the Miller capacitor are close to normal bias conditions. |
