Item Specifications and Additional Information: Positive Voltage Regulators The LM340T-12 is virtually indestructible with it's internal current-limiting, thermal shutdown, and safe-area compensation. This device is designed to be used as a fixed regulator in most instances. When this voltage regulator is used for on-card regulation, noise and distribution problems that may occur with single-point regulation are eliminated. To use the LM340T-12 as an adjustable regulator the use of outside components would be needed. Features: Complete specifications at 1A load Internal thermal overload protection Internal short-circuit current limit Output transistor safe area protection P+ Product Enhancement tested Electrical Specs (0°C ≤ TJ ≤ +125°C unless otherwise specified) Output Voltage: 12V - (TJ = 25°C, 5 mA ≤ IO ≤ 1A) Line Regulation (TJ = 25°C): 4mV typ. Load Regulation : 12mV - (TJ = 25°C, 5 mA ≤ IO ≤ 1.5A) Quiescent Current (TJ = 25°C): 6mA max Output Noise Voltage: 75µV - (TA = 25°C, 10 Hz ≤ f ≤ 100 kHz) Ripple Rejection: 72dB - (TJ = 25°C, f = 120 Hz, IO = 1A) Manufactured by: National Semiconductor Part Number: LM340T-12 Full Datasheet: LM340T-12
