KA79MXX

3-Terminal 0.5A Negative Voltage Regulator

Features

Description

• No external components required

• Output current in excess of 0.5A

• Internal thermal overload

• Internal short circuit current limiting

• Output transistor safe area compensation

• Output voltages of -5V,-6V,-8V, -12V,-15V,-18V,-24V

The KA79MXX series of 3-Terminal medium current

negative voltage regulators are monolithic integrated circuits

designed as fixed voltage regulators. These regulators

employ internal current limiting, thermal shutdown and

safe area compensation making them essentially

indestructible.

Typical Applications

Figure 1. Fixed Output Regulator

Figure 2. Variable Output

Notes:

1. Required for stability. For value given, capacitor must be solid tantalum. 25µF aluminum electrolytic may be substituted.

2. C improves transient response and ripple rejection. Do not increase beyond 50µF.
