3-Terminal Fixed Negative Output Voltage Regulator
ITO-220
Pin assignment:
1. Ground
2. Input
Voltage Range - 5V to - 24V
Output Current up to 1A
3. Output
(Heatsink surface
connected to Pin 2)
General Description
The TS7900 series of fixed output negative voltage regulators are intended as complements to the popular TS7800
series device. These negative regulators are available in the same seven-voltage options as the TS7800 devices. In
addition, one extra voltage option commonly employed in MECL systems is also available in the negative TS7900 Series.
Available in fixed output voltage options from -5.0 to -24 volts, these regulators employ current limiting, thermal shutdown,
and safe-area compensation--making them remarkably rugged under most operating conditions. With adequate
heatsinking they can deliver output currents in excess of 1 ampere.
This series is offered in 3-pin TO-220, ITO-220 package.
Features
Standard Application
Output current up to 1A
No external components required
Internal thermal overload protection
Internal short-circuit current limiting
Output transistor safe-area compensation
Output voltage offered in 4% tolerance
A common ground is required between the input and the
output voltages. The input voltage must remain typically 2.0V
above the output voltage even during the low point on the
Input ripple voltage.
XX = these two digits of the type number indicate voltage.
* = Cin is required if regulator is located an appreciable
distance from power supply filter.
