www.ti.com SNVS244F – SEPTEMBER 2003 – REVISED APRIL 2013 LP3855-ADJ 1.5A Fast Response Ultra Low Dropout Linear Regulators
Check for Samples: LP3855-ADJ FEATURES DESCRIPTION The LP3855-ADJ fast ultra low-dropout linear
regulators operate from a +2.5V to +7.0V input
supply. These ultra low dropout linear regulators
respond very quickly to step changes in load, which
makes them suitable for low voltage microprocessor
applications. The LP3855-ADJ is developed on a
CMOS process which allows low quiescent current
operation independent of output load current. This
CMOS process also allows the LP3855-ADJ to
operate under extremely low dropout conditions. 1 2 Ultra Low Dropout Voltage
Stable with Selected Ceramic Capacitors
Low Ground Pin Current
Load Regulation of 0.06%
10nA Quiescent Current in Shutdown Mode
Specified Output Current of 1.5A DC
Available in DDPAK/TO-263, TO-220 and SOT223 Packages
Overtemperature/Overcurrent Protection
-40В°C to +125В°C Junction Temperature Range Dropout Voltage: Ultra low dropout voltage; typically
24mV at 150mA load current and 240mV at 1.5A load
current. APPLICATIONS Ground Pin Current: Typically 4mA at 1.5A load
current. Microprocessor Power Supplies …
