AX78LXX Datasheet, PDF (1/10 Pages) List of Unclassifed Manufacturers – 3-Terminal Positive Voltage Regulators
AX78LXXAM/BM
AX78LXXAA/BA
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

COUT
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.
