The Design of An LDO Regulator [PDF]
ITM Web of Conferences, 2023 In today’s modern systems on chip (SOCs), a crucial power management circuit is the low-dropout (LDO) regulator. Of course, the need for supply voltage regulation, goes back many years in the past since the circuits have been designed.
