Description

The LP2980IM5-5.0 is a low-dropout (LDO) voltage regulator produced by Texas Instruments. It provides a fixed output voltage of 5.0 volts and is designed for applications requiring low noise and precise regulation. The device operates with an input voltage range typically between 2.1V to 16V and features a low dropout voltage of approximately 50 mV at light loads to 380 mV at 50 mA, making it suitable for battery-powered applications. It offers a maximum output current of 50 mA.
Key features include low output noise, high power supply rejection ratio (PSRR), and low quiescent current, contributing to extended battery life. The LP2980IM5-5.0 also incorporates a thermal shutdown feature and current limiting to protect against overload conditions. It is housed in a small SOT-23-5 package, making it ideal for space-constrained designs. Additionally, it is suitable for applications in portable devices, wireless communication systems, and other electronics needing stable voltage regulation with minimal power loss.

Pinout

The LP2980IM5-5.0 is a low-dropout linear voltage regulator. It is housed in a 5-pin SOT-23 package. Here is the pin configuration and their functions:
1. Pin 1 (GND): Ground. This pin is connected to the ground reference point.
2. Pin 2 (VOUT): Output Voltage. This pin provides the regulated output voltage, which in this case is 5.0V.
3. Pin 3 (SENSE): Sense. This pin is used to sense the output voltage to improve regulation and is typically connected to the load or to the VOUT pin.
4. Pin 4 (SHUTDOWN): Shutdown. This pin is used to enable or disable the regulator. A low voltage on this pin shuts down the regulator, while a high voltage (or left floating) enables it.
5. Pin 5 (VIN): Input Voltage. This pin receives the input voltage from the power supply.
The LP2980IM5-5.0 offers features such as low dropout voltage, low quiescent current, and good load and line regulation, making it suitable for battery-powered applications.
