LP3878-ADJ Micropower 800-mA Low-Noise "Ceramic Stable" Adjustable Voltage
Regulator for 1-V to 5-V Applications Features 3 DescriptionThe LP3878-ADJis an 800-mA, adjustable output, Input Supply Voltage: 2.5Vto 16V voltage regulator designed to provide high• Output Voltage Range:1Vto 5.5V performance and low noisein applications requiring• Designedfor Use With Low-ESR Ceramic output voltagesas lowas1V.
Capacitors Using an optimized VIP (Vertically Integrated PNP)• Very Low Output Noise process, the LP3878-ADJ delivers superior 8-Lead SO PowerPAD™ and WSON Surface- performance:
Mount Packages • Ground Pin Current: Typically 5.5 mAat 800-mA
load, and 180 µAat 100-µA load.• < 10-μA Quiescent Currentin Shutdown Low Power Shutdown: The LP3878-ADJ draws• Low Ground Pin Currentatall Loads less than 10-μA quiescent current when the• Overtemperature and Overcurrent Protection SHUTDOWN pinis pulled low. –40°Cto 125°C Operating Junction Temperature • Precision Output: Ensured output voltageRange accuracyis 1%at room temperature. Low Noise: Broadband output noiseis only 18 μV
