RS78L05
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_C=25C)
 Internal Short-Circuit Current Limiting
 Internal Thermal Overload Protection
 TO-92 & SOT-89 Package

Pin 2: GND
Pin 3: V_IN
Typical Application
Note 1: C_IN is required if regulator is located an
appreciable distance from power supply filter.
Note 2: C_OUT is not needed for stability;
however, it does improve transient response.
Values of less than 0.1uF could cause
instability.
