RS78L12

3-Terminal Positive Voltage Regulators

Description

These regulators employ internal current-limiting and thermal-shutdown, making

them essentially indestructible. They can deliver up to 100mA output current.

Features

 Maximum Output Current of 100mA (T

 Internal Short-Circuit Current Limiting

 Internal Thermal Overload Protection

 TO-92 & SOT-89 Package
