May 11, 2025 · I need Help in a circuit for power selection for esp32 i have 2 options 1)USB_C 5v 2)Battery 4.2V I need circuit in which USB is first priority mean if 5v...
Aug 13, 2020 · What is the difference between BGR and LDO as both give constant DC voltage?
Nov 13, 2024 · I am wondering how we can find the input power of the LDO linear regulator. Consider the following load current and supply voltage to the load. This is also called output current and output voltage of t...
Jun 27, 2019 · Hi I am design one NMOS LDO with current limit function.The dropout of NMOS is 200mV.The supply is set 5.2V,the out is 5V. How can i sense the output current of ldo. Thanks !
Apr 22, 2024 · I'm looking to minimize the frequency variation of an on-chip ring oscillator running at 2MHz, through using either an LDO as its supply voltage, or current-starving it with a current coming from a PTAT...
May 10, 2025 · To prepare more comprehensively, I've thought of a method: sharing my LDO and Bandgap circuit designs and earnestly requesting that seniors here provide questions and feedback on my design.
nmos ldo compensation but in Low Drop-Out Regulator, Pmos is used to achieve lower voltage drop. how can Pmos do that other than Nmos?it seems that lower Ron is not the reason.
Jul 27, 2021 · So in my opinion, having a cascode/folded-cascode EA will simply boost the EA's open loop gain, thus improving the overall PSRR of your LDO. I prefer to over-design my EA with very high open loop gain a...
ldo frequency and transient response Some commercial chips like TI's add comparators to control overshoot and undershoot. When undershoot is detected, sourcing current will be increased and when overshoot is detected,...
Hello, Can anyone suggest the possible value of current source, Vref, VDD, R1, R2, Cload and Rload to me. Because I trying to run a simulation on cadence software based on LDO design. Thanks.
