3-TERMINAL POSITIVE VOLTAGE REGULATOR
Description
The H7812_E series of three-terminal positive regulators are availa-
TO-220
ble in the TO-220AB package. These regulators can provide local on
-card regulation, eliminating the distribution problems associated with single point regulation.
Each employs internal current limiting, thermal shut-down and safe operating area protection,
making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A
output current. Although designed primarily as fixed voltage regulators, these devices can be
used with external components to obtain adjustable voltages and currents.
H7812_E is characterized for operation from 0°C to +125°C, and if operating temperature is
always high, please refer to the power dissipation curve.
Absolute Maximum Ratings (Ta=25°C)
• Input Voltage....................................................................................................................... 35 V
• Total Power Dissipation..................................................................................... Internally limited
• Operating Temperature Range .......................................................................... 0 °C to +125 °C
• Maximum Junction Temperature...................................................................................... 125 °C
• Storage Temperature Range........................................................................... -55 °C to +150 °C
• Lead Temperature (Soldering 10S).................................................................................. 230 °C
