Current Positive Voltage Regulator
Spec. C519M3 Issued Date 2003.04.02 Revised Date Page
PL78L12XM3
SOT-89
Description
PL78L12XM3 series surface mount regulators easy-to-use devices suitable multitude applications that require regulated supply 100mA. These regulators feature internal current limiting thermal shutdown, making them remarkably rugged. external components required with PL78L12XM3 devices many applications. These devices offer substantial performance advantage over traditional zener diode resistor combination, output impedance quiescent current substantially reduced.
