No. : C503A3 Issued Date : 2003.03.21 Revised Date : Page No. : 1/4 PL2950A3 CYStek Product Specification 100mA Low Dropout Voltage Regulators PL2950-XXA3 FEATURES APPLICATIONS • Battery powered systems • High accuracy output voltage • Cordless telephones • Guaranteed 100mA output • Radio control systems • Very low quiescent current • Portable/Palm top/Notebook computers • Low dropout voltage • Portable consumer equipment • Extremely tight load and line regulation • Portable Instrumentation • Very low temperature coefficient • Avionics • Needs only 1µF for stability • Automotive Electronics • Error Flag warns of output dropout • SMPS Post-Regulator • Logic-Controlled electronic shutdown • Voltage Reference • Output programmable from 1.24 to 29V PRODUCT DESCRIPTION ThePL2950-XX is a low power voltage regulator. This device excellent choice for use in battery powered application such as cordless telephone, radio control systems, and portable computers. The PL2950-XX features very low quiescent current (75 µA Typ.) and very low drop output voltage (Typ. 40mV at light load and 380mV at 100mA). This includes a tight initial tolerance of 0.5% typ., extremely good load and line regulation of 0.05% typ., and very low output temperature coefficient, making the PL2950-XX useful as a low-power voltage reference. The error flag output feature is used as power-on reset for warn of a low output voltage, due to following batteries on input. Other feature is the logic-compatible shutdown input which enable the regulator to be switched on and off. The PL2950-XX is offered in 3-pin TO-92 package compatible with other fixed regulator.
