A novel design for a low dropout (LDO) voltage regulator is presented and dedicated to power many sections of a typical cellular handset. However, these baseband, RF, and audio sections have different requirements that influence which LDO is most appropriate. After discussion of the specific requirements, different LDOs are recommended. Also, some LDO(More)
The growth in portable, battery operated devices and other complicated equipments which need high precision supply voltages has fueled the growth of the low dropout regulator(LDO) due to its many advantages[2]. This paper presents a 2.8 V 50 mA on chip low dropout voltage regulator (LDO). The external capacitor is removed allowing for greater power system(More)
This paper presents an enhancement transient capless low dropout voltage regulator (LDO). To eliminate the external capacitor, the miller effect is implemented through the use of a current amplifier. The proposed regulator LDO provides a load current of 50 mA with a dropout voltage of 200 mV, consuming 14μA quiescent current at light loads, and the(More)
This paper presents a high PSRR full on-chip and area efficient low dropout voltage regulator (LDO), exploiting the nested miller compensation technique with active capacitor (NMCAC) to eliminate the external capacitor. A novel technique is used to boost the important characteristic for wireless applications regulators PSRR. The idea is applied to stabilize(More)
This paper present a full on-chip and area efficient low dropout voltage regulator(LDO), exploiting the nested miller compensation with active capacitor (NMCAC) to eliminate the external capacitor and active feedback resistors to reduce the chip area.
