3 Description
The LP2986 is a 200-mA high-precision LDO
regulator with a wide input voltage supply. The device
has two output voltage modes: a fixed-precision
output mode and an adjustable output voltage via an
external resistive divider.
Using an optimized Vertically Integrated PNP (VIP)
process, the LP2986 delivers superior performance:
• Dropout Voltage: Typically 180 mV at 200-mA
load, and 1 mV at 1-mA load.
• GROUND Pin Current: Typically 1 mA at 200-mA
load, and 200 μA at 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 V,
3.3 V, or 3 V with ensured accuracy of 0.5% (A
grade) and 1% (standard grade) at room
temperature.
