| Page No. : 1/10 AX78LXXAM/BM AX78LXXAA/BA 3-Terminal Positive Voltage Regulators AX78LXX Series Pin Assignment 3-Lead Plastic SOT-89 Package Code: M Pin 1: VOUT Pin 2: GND Pin 3: VIN 3-Lead Plastic TO-92 Package Code: A Pin 1: VOUT Pin 2: GND Pin 3: VIN 12 3 1 2 3 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=25C) * Internal Short-Circuit Current Limiting * Internal Thermal Overload Protection * TO-92 & SOT-89 Package Typical Application VIN CIN Absolute Maximum Ratings (TA=25C, Unles Otherwise Specified) Characteristic Input Voltage Power Dissipation Operating Temperature Storage Temperature Junction Temperature Thermal Resistance Symbol VIN PD Topr Tstg Tj Rth(j-a) TO-92 SOT-89 -30 to 85 -55 to 150 150 208 o 1 AX78LXX Series 2 3 VOUT COUT (Note 2) 0.33uF Rating 40 700 500 Unit V mW mW o o o (Note 1) 0.1uF 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.
