† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. If load is returned to a negative power supply, the output must be diode clamped to GND.
2. The PNP pass transistor has a parasitic diode connected between the input and output. This diode normally is reverse biased (VIN > VOUT), but will be forward biased if the output voltage exceeds the input voltage by a diode drop (see Application Information for more details).
3. Maximum power dissipation is a function of TJ(max), JA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) − TA)/JA. Operating at the absolute maximum TJ of 150°C can affect reliability.
4. The package thermal impedance is calculated in accordance with JESD 51-7.


Description

The LP2981DBVR family of fixed-output, low-dropout regulators offers exceptional, cost-effective performance for both portable and nonportable applications. Available in adjustable version and in fixed voltages of 1.8 V, 2.5 V, 2.7 V, 2.8 V, 2.9 V, 3 V, 3.2 V, 3.3 V, 3.6 V, and 5 V, the family has an output tolerance of 0.75% for the A-grade devices (1.25% for the standard grade) and is capable of delivering 100-mA continuous load current. Standard regulator features, such as over-current and over-temperature protection, are included.

The LP2981DBVR has features that make the regulator an ideal candidate for a variety of portable applications:

• Low dropout: A PNP pass element allows a typical dropout of 200 mV at 100-mA load current and 7 mV at 1-mA load.

• Low quiescent current: The use of a vertical PNP process allows for quiescent currents that are considerably lower than those associated with traditional lateral PNP regulators.

• Shutdown: A shutdown feature is available, allowing the regulator to consume only 0.01 µA when the ON/OFF pin is pulled low.

• Small packaging: For the most space-constraint needs, the regulator is available in SOT-23 package and NanoStarTM chip scale packaging. NanoStar package technology is a major breakthrough in IC packaging concepts, using the die as the package.
