The LP2988AIMMX-5.0 meets all of the requirements of the Joint Electron Device Engineering Council(JEDEC) for power supplies and DC-DC converters. It also meets industry standards for space-sensitive applications, such as high-density wiring and complicated pin out schemes.

The LP2988AIMMX-5.0\'s application field covers state-of-the-art low voltage applications such as notebook computers, LCD TV and cellular phones . The provided very quiet operation and low drop out improves the battery life significantly.

LP2988AIMMX-5.0 is a 3-terminal positive linear voltage regulator (PMIC - Voltage Regulators - Linear). It provides a constant regulated output voltage, composed of an error amplifier, a voltage reference, and a series pass transistor. Input voltage is applied to the input pin, the output voltage is taken from the output pin,and the ground pin connects to the system ground.

During operation, an internal error amplifier monitors the output voltage and it compares to the internal reference voltage. When the output voltage drops, the error amplifier commands the pass transistor to increase its current drive until the output voltage is restored to the desired level.

The quiescent current of the LP2988AIMMX-5.0 is 45uA (typical ) and it is optimized to support low-current applications, thus improving the efficiency of the device. The LP2988AIMMX-5.0 also has temperature-compensated internal circuitry that ensures correct operation over a wide temperature range.

The package of the LP2988AIMMX-5.0 is a 3-pin SOT-223 package and the thermal resistance is 160oC/W. The device is rated for a maximum output current of 1 A and a voltage range of 5V. The maximum power dissipation is 3 W.

The LP2988AIMMX-5.0 is designed to operate in a wide range of environmental conditions with low noise, low power consumption and high reliability. It is designed for applications that need low noise and low power consumption, such as notebook computers, LCD TVs and cellular phones. The device provides excellent overload protection and current limiting for long-term reliability.

In conclusion, the LP2988AIMMX-5.0 is a high-performance, super low-noise, low power, low dropout, three-terminal, positive linear voltage regulator. It is designed to deliver full, regulated output current of 1A over a wide input voltage range of 1.7V to 5.5V and a wide temperature range of -40 to 125 degree Celsius. It is suitable for applications such as notebook computers, LCD TVs and cellular phones.
