Three Terminal Medium Current Positive

TO-92

Voltage Regulators

PL78M05XA3

Description

These regulators employ internal current-limiting and thermal-shutdown,

making them essentially indestructible. They can deliver up to 500mA

output current, if the case temperature can be kept at Tc=25°C.

They are intended as fixed voltage regulators in a wide range of applications including local (on-card)

regulation for elimination of noise and distribution problems associated with single-point regulation. In

addition, they can be used with power pass elements to make high-current voltage regulators. The

PL78M05XA3 used as a Zener diode/resistor combination replacement, offers an effective output

impedance improvement of typically two orders of magnitude, along with lower quiescent current and lower

noise.
