LP2986

LP2986 Micropower, 200 mA Ultra Low-Dropout Fixed or Adjustable Voltage Regulator March 1999 LP2986 Micropower, 200 mA Ultra Low-Dropout Fixed or Adjustable Voltage Regulator General Description The LP2986 is a 200 mA precision LDO voltage regulator which offers the designer a higher performance version of the industry standard LP2951. Using an optimized VIP™ (Vertically Integrated PNP) process, the LP2986 delivers superior performance: Dropout Voltage: Typically 180 mV @ 200 mA load, and 1 mV @ 1 mA load. Ground Pin Current: Typically 1 mA @ 200 mA load, and 200 µA @ 10 mA load. Sleep Mode: The LP2986 draws less than 1 µA quiescent current when shutdown pin is pulled low. Error Flag: The built-in error flag goes low when the output drops approximately 5% below nominal. Precision Output: The standard product versions available can be pin-strapped (using the internal resistive divider) to provide output voltages of 5.0V, 3.3V, or 3.0V with guaranteed accuracy of 0.5% (“A” grade) and 1% (standard grade) at room temperature.
