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 (Tc=25°C)
• Internal Short-Circuit Current Limiting
• Internal Thermal Overload Protection
• TO-92 & SOT-89 Package
Absolute Maximum Ratings
(Ta=25°C, Unles Otherwise Specified)

0.1uF
(Note 2)
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.
