The Texas Instruments LM340T12 is a monolithic 3-terminal positive voltage regulator designed for a wide range of applications. It provides a fixed 12V output and can deliver up to 1.5A of current when adequate heat sinking is provided. The regulator incorporates internal current limiting, thermal shutdown, and safe-area compensation, making it highly robust.
Key electrical specifications include an input voltage range of 7.5V to 35V, a typical dropout voltage of 2V, and a quiescent current of 8mA. The device offers good power supply rejection ratio (PSRR) of 50dB at 100kHz and low noise of 40 uVrms.
This component is housed in a TO-220 package suitable for through-hole mounting. The operating temperature range is from 0°C to 125°C. The LM340T-12 is noted as 'Not Recommended for New Designs' (NRND).
Applications for this regulator include local on-card regulation to eliminate noise and distribution problems associated with single-point regulation. It can also be used with external components to achieve adjustable output voltages and currents.
