About this product
A 3 A low-dropout linear voltage regulator from Microchip for high-current loads. It is protected against overcurrent, reversed input polarity, reversed lead insertion and overtemperature, and its low dropout voltage helps it run from a supply close to the output voltage.
Specifications
- Output current
- 3 A
- Dropout voltage
- 350 mV typical at full load (350-425 mV)
- Regulator type
- Low-dropout (LDO) linear regulator / منظم خطي منخفض فرق الجهد
- Protection
- Overcurrent, reversed polarity, overtemperature / تيار زائد وعكس القطبية وارتفاع الحرارة
- Brand
- Microchip
Frequently asked questions
Do I need a heatsink?
At 3 A, power dissipated in the regulator equals (input minus output voltage) times the load current. Calculate this and follow the datasheet's thermal guidance to choose a heatsink.
How do I wire the regulator?
Connect the unregulated input to the input pin, the regulated output to the output pin, and ground to ground, with input and output capacitors as recommended in the datasheet. Confirm the pinout for your exact package.
