Choosing an output capacitor for LDO regulators with PNP or PMOS pass element can be difficult due to specific ESR requirements. This application note explains why higher ESR capacitors are necessary, ...
Some low-dropout regulators (LDOs) use multiple feedback loops to improve output voltage transient response. In many of these cases, some or all of the loops are inside the IC. Accessing these loops ...
Linear Technology's LT3009 is a micropower LDO regulator optimizes stability and transient response with low-ESR, 1-μF ceramic output capacitors. Linear Technology’s LT3009 is a micropower LDO ...
A regulator is a closed-loop feedback system. For the LDO to be stable, the phase margin must be positive. In other words, at unity gain crossover frequency of the gain curve, the phase of the system ...
Power management of battery-powered electronic devices is becoming increasingly more important for the microelectronics industry. This white paper details the difference between low dropout (LDO) ...
