MC7900

Features:

• No External Components Required
• Internal Thermal Overload Protection
• Internal Short Circuit Current Limiting
• Output Transistor SafeArea Compensation
• Available in 2% Voltage Tolerance (See Ordering Information)


Application

A common ground is required between the input and the output voltages. The input  voltage must remain typically 2.0 V above more negative even during the high point of the input ripple voltage.

XX, These two digits of the type number indicate nominal voltage.
** C _in is required if regulator is located an appreciable distance from power supply filter.
** C _O improve stability and transient response.

Description

The MC7900 series of fixed output negative voltage regulators are ntended as complements to the popular MC7800 series devices. These negative regulators MC7900 are available in the same sevenvoltage options as the MC7800 devices. In addition, one extra voltage option commonly employed n MECL systems is also available in the negative MC7900 series.
Available in fixed output voltage options from 5.0 V to 24 V, these egulators employ current limiting, thermal shutdown, and safearea compensation making them remarkably rugged under most operating conditions. With adequate heatsinking they can deliver output currents in excess of 1.0 A.
