Texas Instruments LP3883ES-1.2/NOPBThe LP3883 is a high-current, fast-response regulator which can maintain output voltage regulation with minimum input to output voltage drop. Fabricated on a CMOS process, the device operates from two input voltages: Vbias provides voltage to drive the gate of the N-MOS power transistor, while Vin is the input voltage which supplies power to the load. The use of an external bias rail allows the part to operate from ultra low Vin voltages. Unlike bipolar regulators, the CMOS architecture consumes extremely low quiescent current at any output load current. The use of an N-MOS power transistor results in wide bandwidth, yet minimum external capacitance is required to maintain loop stability.
The fast transient response of these devices makes them suitable for use in powering DSP, Microcontroller Core voltages and Switch Mode Power Supply post regulators. The parts are available in TO-220 and DDPAK/TO-263 packages.
Dropout Voltage:210 mV (typ) @ 3A load current.
Ground Pin Current:3 mA (typ) at full load.
Shutdown Current:60 nA (typ) when S/D pin is low.
Precision Output Voltage:1.5% room temperature accuracy.
