LD1084

LD1084 5 A low-drop positive voltage regulator adjustable TO-220 Datasheet - production data LD1084 quiescent current flows into the load, so to increase the efficiency. A minimum capacitor of 10 µF is needed for stability. The device is supplied in TO-220. The on-chip trimming allows the regulator to reach a very tight output voltage tolerance, within ± 1% at 25 °C. Table 1. Device summary Order code Output voltage LD1084V adjustable Features Typical dropout 1.3 V (at 5 A) Three-terminal adjustable output voltage Guaranteed output current up to 5 A Output tolerance ± 1% at 25 °C and ± 2% in full temperature range Internal power and thermal limit Wide operating temperature range -40 °C to 125 °C Package available: TO-220 Pinout compatibility with standard adjustable VREG Description The LD1084 is a low-drop voltage regulator providing up to 5 A of output current. Dropout is guaranteed at a maximum of 1.5 V at the maximum output current, decreasing at lower loads. The LD1084 is pin-to-pin compatible with the older 3-terminal adjustable regulators, but it has better performances in terms of drop and output tolerance. Unlike PNP regulators, where a part of the output current is wasted as quiescent current, the September 2013 This is information on a product in full production.
