Programmable 1 A ultra-low dropout LDO regulator for high-resolution camera sensors

Original language description

In this article, design and realization of a high-performance linear low dropout regulator (LDO) capable of supplying 1 A of output current, designed and fabricated in 180 nm BCD technology of STMicroelectronics company, is described. The main purpose of this device is providing a stable output voltage for supplying highresolution sensors of cameras in cellphones. The LDO is equipped with a big N-channel power transistor allowing an ultra-low dropout voltage around 50 mV at the maximal load current of 1 A even with a very low level of the output voltage of only 0.4 V. These features make the device suitable as a block following buck switching converters. Emphasis has been laid on assuring 1% accuracy of the output voltage across full temperature range and line and load conditions, very low quiescent current around 32 & mu;A, necessary for battery powered applications such as cellphones, good transient response and a high power supply rejection ratio (PSRR) of more than 85 dB at 1 kHz. This combination of high-level parameters stands for an extraordinary device. The proposed LDO is a programmable device which means that the output voltage (up to 100 voltage versions in total) and other functions can be set via post-package electrical trimming. Last but not least, an efficient design for testability (DFT) is implemented in order to reduce the failed parts to a very low level, guaranteeing the highest quality level needed in the market.
