PMIC - Voltage Regulators - Linear

The LP3999ITLX-2.8/NOPB is an integrated, low power voltage regulator designed for applications requiring very low quiescent current. Advanced process technology and careful circuit design combine to provide low operating current in both drop-out and regulation modes.

General Features

• High output accuracy: ≤ ±2.0% over load and line
• Wide range of operating voltage: 2.8V to 17V
• Low quiescent current: 180μA (typical value)
• Optional flying capacitor
• Integrated option for low ESR capacitor
• High power supply rejection ratio (PSRR): 70dB (typical value)
• Wide temperature range: -40°C to +125°C

Application Field

The LP3999ITLX-2.8/NOPB provides adjustable and fixed voltage output, making it ideal for use in all kinds of mobile devices, such as wireless networks, communications, mobile phones, tablets, etc. It can also be used in automotive and industrial applications, where voltage regulation accuracy and low power consumption are important design considerations.

Working Principle

The LP3999ITLX-2.8/NOPB features two control pins: Output Voltage Select (OVS) and Close-Loop Enable (CLE) for wide voltage output range regulation. In the drop-out mode, OVS must be connected to the common ground for regulation, the output voltage will follow the input voltage (VIN) within output voltage accuracy range and the CLE must be kept at low voltage to reduce the quiescent current. In the regulating mode, OVS can be adjusted between 2.8V to 17V with external resistor voltage divider and CLE must be kept at high voltage to enable the regulation. The output voltage is monitored internally and this is used to adjust the output through a 3-terminal regulation loop, which keeps the output voltage accurate, fast and stable.

Package

The LP3999ITLX-2.8/NOPB is available in an 8-pin plastic QFN package, 6-pin SOT-23 package and 8-pin SOIC package. The device has a low profile package and small pad size, making it suitable for a wide range of applications where space is limited.

Conclusion

The LP3999ITLX-2.8/NOPB is an integrated, low power voltage regulator designed for a wide range of applications where voltage regulation accuracy and low power consumption are important design considerations. It features two control pins for wide voltage output range regulation and a wide temperature range for reliable operation. Additionally, the device has a low profile package and small pad size, making it suitable for applications where space is limited. The LP3999ITLX-2.8/NOPB is an ideal choice for all kinds of mobile devices, automotive and industrial applications.
