Available in voltages of 1.25 V, 1.35 V, 1.5 V, 1.7 V, 1.8 V, and 2 V, the family has an output tolerance of 1% for the A version (1.5% for the non-A version), and is capable of delivering 150-mA continuous load current. Standard regulator features, such as over-current and over-temperature protection, are included. The LP2985LV has a host of features that makes the regulator an ideal candidate for a variety of portable applications: • Low dropout: A PNP pass element allows a typical dropout of 280 mV at 150-mA load current. • 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. • Low-ESR-capacitor friendly: The regulator is stable with low ESR capacitors, allowing for the use of small, inexpensive ceramic capacitors in cost-sensitive applications.
