Description:

Series 3-Terminal Positive Regulators

Features

* n Complete specifications at 1A load n Output voltage tolerances of ±2% at Tj = 25˚C and ±4% over the temperature range (LM140A/LM340A) n Line regulation of 0.01% of VOUT/V of ∆VIN at 1A load (LM140A/LM340A) n Load regulation of 0.3% of VOUT/A (LM140A/LM340A) n Internal thermal overload protection n

Applications

* including local (on-card) regulation for elimination of noise and distribution problems associated with single-point regulation. In addition to use as fixed voltage regulators, these devices can be used with external components to obtain adjustable output voltages and currents. Considerable effort w
