Package

The LD2985BM50R is a low-dropout linear regulator packaged in a SO-8 (Small Outline) package. This package type is suitable for surface-mount applications, offering a compact design and enhanced thermal performance.

Pinout

The LD2985BM50R is a low-dropout (LDO) voltage regulator manufactured by STMicroelectronics. It typically comes in a SOT-23-5 package, which has 5 pins. Here is a brief description of its pin functions:
1. GND (Pin 1): Ground reference for the regulator.
2. VIN (Pin 2): Input voltage supply pin. The input voltage must be higher than the desired output voltage plus the dropout voltage.
3. EN (Pin 3): Enable pin. This pin enables the device when a high voltage is applied and disables it when low.
4. NC (Pin 4): No internal connection. This pin is often not used and may be tied to ground to avoid floating.
5. VOUT (Pin 5): Output voltage pin, providing a regulated output voltage.
The LD2985BM50R is specifically for a fixed output voltage of 5.0V. It is designed for applications requiring a regulated voltage with low noise and low dropout, suitable for use in battery-powered devices and other portable electronics.
