there is still room for domestic breakthroughs in high - end fields, and the situation of import dependence needs to be improved. With the acceleration of the domestic substitution process, Corebai Microelectronics, a domestic R & D team, has made breakthroughs in high - voltage ...
where A V is the open-loop gain of the regulator feedback loop, and A VO is the gain from V IN to V OUT with the regula-tor feedback loop open. From this equation it can be seen PSRR A A V VO =20log ,PSRR Ripple Ripple Input Output =20log .that to increase the PSRR it is...
Understanding the Terms and Definitions of LDO Voltage Regulators 3 SLVA079 EN (high) + Is V CC Vi Reference V ref V CC – + – GND Standby current = I s when output is disabled Switch positions are shown with EN high (standby mode) – V o =0[V] + Figure 4. Standby Current of...
Buck 3 will go back to its previous state 8.4.7.6 Device Sleep (DEVSLP) Programming via SPI There is no bit which has the same function as DEVSLP terminal. Disabling or programming the Bucks to new level is the user's decision based on power consumption and other requirements The following...
In many cases, the linear regulator has to provide voltages to devices which need the reset function, like a MCU: this is provided by the LDOOK output, that is pulled low when VOUTLDO goes below a threshold. Once VOUTLDO returns above tha...
The dropout voltage, expressed in terms of RDSON and load current, is VDROPOUT = ILOAD× RDSON RDSON includes resistance from the pass element, on-chip interconnects, leads, and bond wires, and can be estimated by the LDO’s dropout voltage. For example, the ADP151 in the WLCSP has a ...
