LP3872, LP3875SNVS227H –FEBRUARY 2003–REVISED JANUARY 2015
LP387x 1.5-A Fast Ultra-Low-Dropout Linear Regulators Features 3 DescriptionThe LP387x seriesof fast ultra low-dropout linear Input Voltage Range: 2.5Vto7V regulators operate froma 2.5-Vto 7-V input supply.• Ultra Low-Dropout Voltage Wide range of preset output voltage options are• Low Ground Pin Current available. These ultra low-dropout linear regulators
respond very quicklyto step changesin load, which• Load Regulationof 0.06% makes them suitable for low-voltage microprocessor• 10-nA Quiescent Currentin Shutdown Mode applications. The LP3872 and LP3875 are developed• Ensured Output Currentof 1.5-A DC ona CMOS process which allows low quiescent
current operation independentof output load current.• Availablein DDPAK/TO-263, TO-220, and
This CMOS process also allows the LP3872 andSOT-223 Packages
LP3875 to operate under extremely low dropout• Output Voltage Accuracy± 1.5% conditions.• ERROR Flag for Output Status
Dropout Voltage: Ultra low-dropout voltage; typically• Sense Option Improves Load Regulation 38 mVat 150-mA load current and 380 mVat 1.5-A• Minimum Output Capacitor Requirements load current. Overtemperature/Overcurrent Protection
Ground Pin Current: Typically6 mAat 1.5-A load• −40°Cto 125°C Junction Temperature Range current.
Shutdown Mode: Typically 10-nA quiescent current
2 Applications when the SD pinis pulled low. Microprocessor Power Supplies
ERROR Flag: ERROR flag goes low when the output• GTL, GTL+, BTL, and SSTL Bus Terminators voltage drops 10% below nominal value (LP3872 Power Supplies for DSPs only). SCSI Terminators
SENSE: Sense pin improves regulation at remote Post Regulators loads (LP3875 only). High Efficiency Linear Regulators
Precision Output Voltage: Multiple output voltage
options are available ranging from 1.8Vto5V witha• Battery Chargers
