Description
3-Lead Plastic TO-92
Package Code: A
Pin 1: VOUT
Pin 2: GND
Pin 3: VIN
These regulators employ internal current-limiting and thermal-shutdown, making
them essentially indestructible. They can deliver up to 100mA output current.
Features

Note 1: CIN is required if regulator is located an
appreciable distance from power supply filter.
Note 2: COUT is not needed for stability;
however, it does improve transient response.
Values of less than 0.1uF could cause
instability.
