Description
The Bay Linear LM78MXX is integrated linear positive
regulator with three terminals. The LM78MXX offer several
fixed output voltages making them useful in wide range of
applications. When used as a zener diode/resistor combination
replacement, the LM78MXX usually results in an effective
output impedance improvement of two orders of magnitude,
lower quiescen t current.
The LM78MXX is available in the TO-220, TO-263 &
TO-252 packages,
Features
• Output Current of 500mA
• Internal thermal overload protection
• Internal Short-Circuit Limited
• No External Component
• Output Voltage 5.0V, 6V, 8V, 9V, 10V,
12V, 15V
• Offer in plastic TO-220 & TO-252
• Direct Replacement for LM78MXX
Applications
• Post regulator for switching DC/DC
converter
• Bias supply fo r analog circuits
