TS78M00 Series

Taiwan Semiconductor

1 Version: F1512

3-Terminal 500mA Positive Voltage Regulator

DESCRIPTION

The TS78M00 Series positive voltage regulators are

identical to the popular TS7800 Series devices, except

that they are specified for only half the output current.

Like the TS7800 devices, the TS78M00 Series 3-

Terminal regulators are intended for local, on-card

voltage regulation. Internal current limiting, thermal

shutdown circuitry and safe-area compensation for the

internal pass transistor combine to make these devices

remarkably rugged under most operating conditions.

Maximum output current with adequate heatsink is

500mA

FEATURES

● Output Voltage Range 5V & 12V

● Output current up to 500mA

● No external components required

● Internal thermal overload protection

● Internal short-circuit current limiting

● Output transistor safe-area compensation

● Output voltage offered in 4% tolerance

● Compliant to RoHS Directive 2011/65/EU and

WEEE 2002/96/EC

● Halogen-free according to IEC 61249-2-21

APPLICATION

● Switching power supply

● Home appliance

TYPICAL APPLICATION CIRCUIT

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.

** = Co is not needed for stability; however, it does improve transient response.
