Low overshoot, low dropout voltage regulator with level detector
2010 IEEE Dallas Circuits and Systems Workshop, 2010An ultra-small, low power, low dropout (LDO) voltage regulator is presented which tracks the output voltage with threshold voltages of the underlying process technology. The topology of the regulator is extremely simple because it does not use an error amplifier.

Cascoded OTA based low dropout (LDO) voltage regulator
Proceedings of the 2014 IEEE Emerging Technology and Factory Automation (ETFA), 2014This article aims to present the design of a 4.5- V, 450-mA low drop-out (LDO) voltage linear regulator based on a two-stage cascoded operational transconductance amplifier (OTA) as error amplifier. The aforementioned two-stage OTA is designed with cascoded current mirroring technique to boost up the output impedance.

Radiation induced change of serial pnp power transistor's dropout voltage in voltage regulators
2012Previous examinations of voltage regulators "National Semiconductor" LM2940CT5 and "STMicroelectronics" L4940V5 in gamma radiation field pointed on similar influences of serial pnp transistor's geometry and its perimeter-to-area ratio on degradation of the transistor's forward emitter current gain.
