1 / 20 page LM340, A Series SEMICONDUCTOR TECHNICAL DATA THREE–TERMINAL POSITIVE FIXED VOLTAGE REGULATORS Order this document by LM340/D Pin 1. Input 2. Ground 3. Output T SUFFIX PLASTIC PACKAGE CASE 221A Heatsink surface is connected to Pin 2. 3 1 2 Simplified Application A common ground is required between the input and the output voltages. The input voltage must remain typically 1.7 V above the output voltage even during the low point on the input ripple voltage. XX these two digits of the type number indicate voltage. *Cin is required if regulator is located an appreciable distance from power supply filter. ** CO is not needed for stability; however, it does improve transient response. If needed, use a 0.1 µF ceramic disc. LM340–XX Input Cin* 0.33 µF CO** Output 1 MOTOROLA ANALOG IC DEVICE DATA Three-Terminal Positive Fixed Voltage Regulators This family of fixed voltage regulators are monolithic integrated circuits capable of driving loads in excess of 1.0 A. These three–terminal regulators employ internal current limiting, thermal shutdown, and safe–area compensation. Devices are available with improved specifications, including a 2% output voltage tolerance, on A–suffix 5.0, 12 and 15 V device types. Although designed primarily as a fixed voltage regulator, these devices can be used with external components to obtain adjustable voltages and currents. This series of devices can be used with a series–pass transistor to boost output current capability at the nominal output voltage. • Output Current in Excess of 1.0 A • No External Components Required • Output Voltage Offered in 2% and 4% Tolerance* • Internal Thermal Overload Protection • Internal Short Circuit Current Limiting • Output Transistor Safe–Area Compensation ORDERING INFORMATION Device Output Voltage and Tolerance Operating Temperature Range Package LM340T–5.0 5.0 V ± 4% T 0 12 C Pl i P LM340AT–5.0 5.0 V ± 2% T 0 12 C Pl i P LM340T–6.0 6.0 V ± 4% T 0 12 C Pl i P LM340T–8.0 8.0 V ± 4% T 0 12 C Pl i P LM340T–12 12 V ± 4% TJ =0° to +125°C Plastic Power LM340AT–12 12 V ± 2% TJ = 0° to +125°C Plastic Power LM340T–15 15 V ± 4% LM340AT–15 15 V ± 2% LM340T–18 18 V ± 4% LM340T–24 24 V ± 4% * 2% regulators are available in 5, 12 and 15 V devices. © Motorola, Inc. 1996 Rev 1 |
