1FEATURES DESCRIPTION
The LP3883isa high-current, fast-response regulator Ultra Low Dropout Voltage (210 mV@ 3A typ) which can maintain output voltage regulation with• Low Ground Pin Current minimum inputto output voltage drop. Fabricated on Load Regulationof 0.04%/A a CMOS process, the device operates from two input
voltages: Vbias provides voltageto drive the gateof• 60 nA Typical Quiescent Currentin Shutdown the N-MOS power transistor, while Vinis the input• 1.5% Output Accuracy (25°C) voltage which supplies powerto the load. The useof• TO-220, DDPAK/TO-263 Packages an external bias rail allows the partto operate from
ultra low Vin voltages. Unlike bipolar regulators, the• Over Temperature/over Current Protection CMOS architecture consumes extremely low• −40°Cto +125°C Junction Temperature Range quiescent currentat any output load current. The use an N-MOS power transistor results in wideAPPLICATIONS bandwidth, yet minimum external capacitance is
requiredto maintain loop stability.• DSP Power Supplies Server Core and I/O Supplies The fast transient responseof these devices makes
them suitable for use in powering DSP,• Linear Power Supplies for PC Add-in-Cards Microcontroller Core voltages and Switch Mode• Set-Top Box Power Supplies Power Supply post regulators. The parts are available• Microprocessor Power Supplies in TO-220 and DDPAK/TO-263 packages. High Efficiency Linear Power Supplies Dropout Voltage: 210 mV (typ)@ 3A load current. SMPS Post-Regulators Ground Pin Current:3 mA (typ)at full load.
Shutdown Current:60 nA (typ) when S/D pinis low.
