CYStech Electronics Corp. Spec. 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 (75µA Typ.) and very low drop output voltage (Typ. 40mV at light load and 380mV 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.

Note 2:Unless otherwise specified all limits guaranteed for TJ=25℃,Vin=V o+1V ,IL=100μA and CL=1μF. Note 3.Regulations is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in output voltage due to heating effects are covered under the specification for thermal regulation. Note 4:Dropout voltage is defined as the input to output differential at which the output voltage drops 100mV below its nominal value measured at 1V differential. At very low values of programmed output voltage, the mini- mum input supply voltage of 2V(2.3V over temperature) must be taken into account.
