LD1085CDT-R STMicroelectronics

LD1085C 3 A low-drop, adjustable positive voltage regulator Datasheet - production data The device is supplied in DPAK. The on-chip trimming allows the regulator to reach a very tight output voltage tolerance, within 2% at 25 C. Table 1. Device summary Order code Package DPAK LD1085CDT-R DPAK (tape and reel) Features Typical dropout 1.3 V (at 3 A) 3-terminal adjustable output voltage Guaranteed output current up to 3 A Output tolerance 2% at 25 C and 3% in full temperature range Internal power and thermal limit Wide operating temperature range -40 C to 125 C Package available: DPAK Pinout compatibility with standard adjustable VREG Description The LD1085C is a low-drop voltage regulator, providing up to 3 A of output current.The dropout is guaranteed to be as low as 1.5 V at the maximum current and it decreases at lower loads. The LD1085C is pin-to-pin compatible with the old 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 LD1085C quiescent current flows into the load, so to increase the efficiency. A minimum capacitor of 10 F is needed for stability.
