Package
The LP3982ILD-3.3 is a low-dropout (LDO) linear voltage regulator. It is typically housed in a small-outline transistor (SOT) package, specifically SOT-23-5, which is a compact, surface-mount package designed for efficient heat dissipation and space-saving on printed circuit boards.
Pinout
The LP3982ILD-3.3 is a low-dropout (LDO) voltage regulator. It typically comes in a 5-pin DSBGA (Die Size Ball Grid Array) package. The primary function of this device is to provide a stable 3.3V output voltage from a higher input voltage with low dropout and low quiescent current. It is designed for portable and battery-powered applications where efficiency and compact size are crucial.
The pin functions generally include:
1. VIN: Input voltage supply.
2. GND: Ground connection.
3. VOUT: Regulated output voltage (3.3V for this model).
4. EN: Enable pin to turn the regulator on or off.
5. NC (or optional feedback): No connection or sometimes used for feedback.
For detailed specifications and additional features, it's important to consult the manufacturer's datasheet.
