LP3876-ADJ
www.ti.com SNVS245C – SEPTEMBER 2003 – REVISED APRIL 2013 LP3876-ADJ 3A Fast Ultra Low Dropout Linear Regulator
Check for Samples: LP3876-ADJ FEATURES DESCRIPTION The LP3876-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 LP3876-ADJ is developed on a
CMOS process which allows low quiescent current
operation independent of output load current. This
CMOS process also allows the LP3876-ADJ to
operate under extremely low dropout conditions. 1 2 Ultra Low Dropout Voltage
Low Ground Pin Current
Load Regulation of 0.08%
1ВµA Quiescent Current in Shutdown Mode
Specified Output Current of 3A DC
Available in DDPAK/TO-263 and TO-220
Packages
Minimum output Capacitor Requirements
Overtemperature/Overcurrent Protection
-40В°C to +125В°C Junction Temperature Range Dropout Voltage: Ultra low dropout voltage; typically
80mV at 300mA load current and 800mV at 3A load
current. APPLICATIONS Ground Pin Current: Typically 6mA at 3A load …
