The MCP1825/MCP1825S is a 500 mA Low Dropout (LDO) linear regulator that provides high current and low output voltages. The MCP1825 comes in a fixed or adjustable output voltage version, with an output voltage range of 0.8 V to 5.0 V. The 500 mA output current capability, combined with the low output voltage capability, make the MCP1825 a good choice for new sub-1.8 V output voltage LDO applications that have high current demands. The MCP1825S is a 3-pin fixed voltage version. **Features:**
DESCRIPTION The LD1085 is a LOW DROP Voltage Regulator able to provide up to 3A of Output Current. Dropout is guaranteed at a maximum of 1.2V a the maximum output current, decreasing at lower loads. The LD1085 is pin to pin compatible with the older 3-terminal adjustable regulators, but has better performances in term of drop and output tolerance. A 2.85V 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 LD1085 quiescent current flows into the load, so increase efficiency. Only a 10µF minimum capacitor is need for stability. The device is supplied in TO-220, TO-220FP, D2PAK and D2PAK/A. On chip trimming allows the regulator to reach a very tight output voltage tolerance, within ±1% at 25°C. ■ TYPICAL DROPOUT 1.3V (AT 3A) ■ THREE TERMINAL ADJUSTABLE OR FIXED OUTPUT VOLTAGE 1.5V, 1.8V, 2.5V, 2.85V, 3.3V, 3.6V, 5V, 8V, 9V, 12V. ■ GUARANTEED OUTPUT CURRENT UP TO 3A ■ OUPUT 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, TO-220FP D2PAK, D2PAK/A ■ PINOUT COMPATIBILITY WITH STANDARD ADJUSTABLE VREG
