A circuit for converting an input voltage to a substantially stable DC voltage for application to a load (40) comprising: (a) at least one branch including: (i) a voltage reference subcircuit (110) capable of maintaining a substantially fixed reference voltage; (ii) a voltage divider (120)...
Additionally, the drooping type current limiter provides excellent control of the current limit value. With the Type C voltage regulator, the current limit value is constant when the output voltage is 1V or higher, so the heater generation is greater than with Types A and B, so there is a ...
This paper introduces the design of a l.8 V low dropout voltage regulator (LDO) and a foldback current limit circuit which limits the output current to 3 mA when load over-current occurs. The LDO was implemented in a 0.18 μm CMOS technology. The measured result reveals that the LDO s ...
