As portable electronics constantly find their way into the hands of eager consumers, the
demands placed on these products and their circuits are ever increasing. More features and more
performance are continuously demanded by consumers. This feature-driven market has brought
with it several constraints on the type of circuits utilized in developing these portable devices.
Cell-Phones, PDA's, MP3 players and various other portable electronics require different
voltage levels to power different architectures that realize the many features within the device.
This work demonstrates a technique to design Programmable Low Power Low Dropout
Voltage Regulators (LDO). The LDO proposed in this research utilizes a fast-transient feedback
loop in order to improve transient response and guarantee stability in all the programmable
output levels. Specifically, the main parameters to be improved are stability over the entire load
current range, reduced overshoot and undershoot variations in transient response, reduction of
LDO deflection voltage, minimization of standby current and low voltage (Vin = 1.2V)
operation.
