1FEATURES DESCRIPTION

The LP3892isa high current, fast response regulator Ultra Low Dropout Voltage (140 mVat 1.5A which can maintain output voltage regulation withtyp) minimum inputto output voltage drop. Fabricated on• Low Ground Pin Current a CMOS process, the device operates from two input Load Regulationof 0.04%/A voltages: Vbias provides voltageto drive the gateof
the N-MOS power transistor, while Vinis the input• 60 nA Typical Quiescent Currentin Shutdown voltage which supplies powerto the load. The useof• 1.5% Output Accuracy (25°C) an external bias rail allows the partto operate from TO-220, DDPAK/TO-263 and SO PowerPAD-8 ultra low Vin voltages. Unlike bipolar regulators, the
Packages
CMOS architecture consumes extremely low
quiescent currentat any output load current. The use• Over Temperature/Over Current Protection of an N-MOS power transistor results in wide• −40°Cto +125°C Junction Temperature Range bandwidth, yet minimum external capacitance is
requiredto maintain loop stability.APPLICATIONS The fast transient responseof these devices makes• DSP Power Supplies them suitable for use in powering DSP,
