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
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.
