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 (Tc=25°C)

• Internal Short-Circuit Current Limiting

• Internal Thermal Overload Protection

• TO-92 & SOT-89 Package

Note 2: C_OUTis not needed for stability;

however, it does improve transient

response. Values of less than 0.1uF could

cause instability.
