drop positive voltage regulator adjustable fixed
Typical dropout 1.3V Three terminal adjustable fixed output voltage 1.8V, 2.5V, 3.3V. Guaranteed output current Output tolerance 25°C full temperature range version Output tolerance 25°C full temperature range internal power thermal limit Wide operating temp. range -40°C 125°C Package available: TO-220, D2PAK, DPAK Pinout compatibility with standard adjustable VREG
D2PAK TO-220 DPAK
Description
KD1084 DROP Voltage Regulator able provide Output Current. Dropout guaranteed maximum 1.5V maximum output current, decreasing lower loads. KD1084 compatible with older 3-terminal adjustable regulators
better performances term drop output tolerance. 2.85V output version suitable SCSI-2 active termination. Unlike regulators, where part output current wasted quiescent current, KD1084 quiescent current flows into load, increase efficiency. Only 10µF minimum capacitor need stability. devices supplied TO-220, D2PAK DPAK. chip trimming allows regulator reach very tight output voltage tolerance, within 25°C version 25°C standard version.
