PMIC - Voltage Regulators - Linear

The LP2985-50DBVR is a low-dropout (LDO) Linear Voltage Regulator designed for battery-powered distributed power systems. This regulator is capable of supplying up to 50mA of current and can be used for a variety of different applications. It is designed to minimize supply current and noise, and offers protection from electrical disturbances due to input voltage and temperature variations.

Application Field

The LP2985-50DBVR is primarily used in low-voltage, battery-powered systems. Some applications of this component and the associated benefits include:

• Portable Digital Devices: When powering a portable device, such as a smartphone or tablet, it is important to maintain a stable output voltage in order to protect the device from fluctuations in battery voltage. This component provides very low output regulation and dropout voltage, ensuring the device’s power supply is reliable. It can also be used in wearable devices, such as fitness trackers and smartwatches.
• Sensor Systems: Many sensor systems require a reliable, low-noise output voltage to accurately detect signals. This component provides excellent noise suppression, making it ideal for use in these applications.
• Power-Saving Devices: Due to its low quiescent current and low dropout voltage, the LP2985-50DBVR is well-suited for use in power-saving devices, such as power management ICs and LED drivers.

Working Principle

The LP2985-50DBVR is a Low Drop-Out (LDO) voltage regulator, which means that it is able to regulate an output voltage with a very low input-to-output differential. The component works by first amplifying the difference between the input voltage and output voltage. This amplified voltage is then used to control the gate voltage of a N-channel MOSFET, which is used to regulate the output voltage. The MOSFET allows current to flow to the output when the voltage is below the threshold set by the amplified difference signal.The component also includes an Over-Voltage Protection (OVP) circuit and an Over-Temperature Protection (OTP) circuit. The OVP helps to protect the component from being damaged if the output voltage exceeds a certain limit, while the OTP prevents it from being damaged due to excessive heat.The LP2985-50DBVR can be used for a variety of applications, but is particularly well-suited for portable digital devices, sensor systems, and power-saving devices. Its low dropout voltage and excellent noise suppression ensure that it is able to accurately and reliably provide a stable output voltage.
