概要

Description

The LD2985BM50R is a low-dropout (LDO) linear voltage regulator designed to provide a stable 5V output from a higher voltage input supply. It features a low dropout voltage, which makes it efficient for battery-powered devices by minimizing power loss. The device is housed in a compact SOIC-8 package, making it suitable for space-constrained applications.
Key characteristics of the LD2985BM50R include a maximum output current of 150mA, a dropout voltage of approximately 200mV at 150mA load, and low quiescent current, enhancing battery life. It also offers protection features like current limiting and thermal shutdown to safeguard against overcurrent conditions and excessive heat.
The regulator is commonly used in consumer electronics, portable devices, and applications where stable voltage is critical. Its ease of use, requiring minimal external components, makes it a popular choice for designers looking to implement efficient power regulation in their circuits.

2. Dropout Voltage: It features a low dropout voltage of about 200 mV at a full load of 150 mA.
3. Maximum Output Current: The regulator supports an output current of up to 150 mA.
4. Low Quiescent Current: It has a low quiescent current, making it suitable for battery-powered applications.
5. Stability: Requires only a small ceramic capacitor for stability.
6. Protection: Includes features such as current limit, thermal shutdown, and reverse polarity protection.
7. Operating Temperature Range: Typically operates within a temperature range of -40°C to +125°C.
8. Package: Available in an SOT-23 package, which is compact and suitable for space-constrained applications.
These features make the LD2985BM50R ideal for use in portable devices, consumer electronics, and other applications where efficient power regulation is needed.

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.
