LP2986SNVS137I –MARCH 1999–REVISED SEPTEMBER 2015
LP2986 Micropower, 200-mA Ultra-Low-Dropout Fixed or Adjustable Voltage Regulator Features 3 DescriptionThe LP2986 is a 200-mA high-precision LDO Wide Supply Voltage Range (16V Maximum) regulator witha wide input voltage supply. The device• Ultra-Low-Dropout Voltage has two output voltage modes:a fixed-precision• 0.5% Output Voltage Accuracy(A Grade) output mode and an adjustable output voltage via an
external resistive divider.• Ensured 200-mA Output Current < 1-μA Quiescent Current when Shutdown Using an optimized Vertically Integrated PNP (VIP)
process, the LP2986 delivers superior performance:• Low GROUND Pin CurrentatAll Loads Dropout Voltage: Typically 180 mV at 200-mA• High Peak Current Capability (400 mA Typical) load, and1 mVat 1-mA load.• Overtemperature/Overcurrent Protection • GROUND Pin Current: Typically1 mAat 200-mA• −40°Cto +125°C Junction Temperature Range load, and 200 μAat 10-mA load. Sleep Mode: The LP2986 draws less than1 μA
2 Applications quiescent current when SHUTDOWN pinis pulled
low.• Cellular Phones ERROR Flag: The built-in ERROR flag goes low• Palmtop/Laptop Computers when the output drops approximately 5% below• Camcorders, Personal Stereos, Cameras nominal. Precision Output: The standard product versions
available can be pin-strapped (using the internal
resistive divider)to provide output voltagesof5V,
3.3V,or3V with ensured accuracyof 0.5% (A
grade) and 1% (standard grade) at room
temperature.
