KD1084xx KD1084Axx
5 A low drop positive voltage regulator adjustable and fixed
Features

Typical dropout 1.3 V (at 5 A) Three terminal adjustable or fixed output voltage 1.8 V, 2.5 V, 3.3 V. Guaranteed output current up to 5 A Output tolerance 1% at 25 C and 2% in full temperature range for the "A" version Output tolerance 2% at 25 C and 3% In full temperature range internal power and thermal limit Wide operating temp. range -40 C to 125 C Package available: TO-220, D2PAK, DPAK Pinout compatibility with standard adjustable VREG A 2.85 V output version is suitable for SCSI-2 active termination. Unlike PNP regulators, where a part of the output current is wasted as quiescent current, the KD1084xx quiescent current flows into the load, so increase efficiency. Only a 10 F minimum capacitor is need for stability. The devices are supplied in TO-220, D2PAK and DPAK. On chip trimming allows the regulator to reach a very tight output voltage tolerance, within 1% at 25 C for "A" version and 2% at 25 C for standard version.

Description
The KD1084xx is a LOW DROP voltage regulator able to provide 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 KD1084xx is pin to pin compatible with he older 3-terminal adjustable regulators but has better performances in term of drop and output tolerance. Table 1. Device summary
