Part Overview
Description
The LP396x series of fast ultra-low-dropout linear regulators operate from a 2.5-V to 7.0-V input supply. A wide range of preset output voltage options are available. These ultra-low dropout linear regulators respond very fast to step changes in load which makes them suitable for low-voltage microprocessor applications. The LP3961/LP3964 are developed on a CMOS process which allows low quiescent current operation independent of output load current. This CMOS process also allows the LP3961/LP3964 to operate under extremely low dropout conditions.
Features
Input Supply Voltage: 2.5 V to 7 V
Ultra-Low Dropout Voltage
Low Ground Pin Current
Load Regulation of 0.02%
15-μA Quiescent Current in Shutdown Mode
Specified Output Current of 0.8-A DC
Available in SOT-223, SFM/TO-263, and TO-220 Packages
Output Voltage Accuracy ±1.5%
ERROR Flag Indicates Output Status (LP3961)
Sense Option Improves Better Load Regulation (LP3964)
Extremely Low Output Capacitor Requirements
Overtemperature and Overcurrent Protection
-40°C to 125°C Junction Temperature Range
Applications
Microprocessor Power Supplies
GTL, GTL , BTL, and SSTL Bus Terminators
Power Supplies for DSPs
SCSI Terminator
Post Regulators
High-Efficiency Linear Regulators
Battery Chargers
Other Battery-Powered Applications
