LDO is a High Performance 100mA Low Dropout regulator. It has soft start function and power-good output. Also it is good power supply rejection ratio without reference bypass capacitor.
This LDO is optimized for a wide variety of applications by supporting an input voltage range from 2.8 V to 5.0 V and an externally adjustable output range of 0.55 V to 3.3 V. The low output voltage enables this LDO to power the modern microcontrollers with lower core voltages.
20mA LDO Regulator
This LDO is a linear voltage regulator for embedded application that requires an internal power supply lower than the external power supply voltage. It is operated by 3.3V and delivers a steady output of 1.2V +/- 5%. The regulator is equipped with bandgap voltage reference and tunable output voltage circuit.
LDO with load tracking LHP zero technique
This work implement low drop out (LDO) regulator based on load tracking LHP zero technique. It consist of bandgap reference, Error amplifier, pass transistor, load tracking LHP zero. Fig. 1 shows the LDO block diagram. The proposed LDO has load tracking LHP zero compensation so LDO’s Load variation is not effect on L..
High PSRR Low Drop Regulator
Low-dropout regulator (LDO) with high PSRR is a suitable choice as a post regulator for switched-mode DC-DC converter to provide clean voltage source. A CMOS low-dropout regulator (LDO) with high power-supply rejection ratio (PSRR) achieved by the proposed supply ripple feed-forward path is presented in this paper.No e..
