FEATURES

DESCRIPTION

The LP2986 is a 200 mA precision LDO voltage

• Ultra Low Dropout Voltage

regulator which offers the designer a higher

• Ensured 200 mA Output Current

performance version of the industry standard LP2951.

• SOIC-8 and VSSOP-8 Surface Mount Packages

Using an optimized VIP™ (Vertically Integrated PNP)

• <1 μA Quiescent Current when Shutdown

process, the LP2986 delivers superior performance:

• Low Ground Pin Current at All Loads

Dropout Voltage: Typically 180 mV @ 200 mA load,

• 0.5% Output Voltage Accuracy (“A” Grade)

and 1 mV @ 1 mA load.

• High Peak Current Capability (400 mA Typical)

Ground Pin Current: Typically 1 mA @ 200 mA

• Wide Supply Voltage Range (16V Max)

load, and 200 μA @ 10 mA load.

• Overtemperature/Overcurrent Protection

Sleep Mode: The LP2986 draws less than 1 μA

• −40°C to +125°C Junction Temperature Range

quiescent current when shutdown pin is pulled low.

Error Flag: The built-in error flag goes low when the

APPLICATIONS

output drops approximately 5% below nominal.

• Cellular Phone

Precision Output: The standard product versions

• Palmtop/Laptop Computer

available can be pin-strapped (using the internal

resistive divider) to provide output voltages of 5.0V,

• Camcorder, Personal Stereo, Camera

3.3V, or 3.0V with ensured accuracy of 0.5% (“A”

grade) and 1% (standard grade) at room temperature.

LP2986 SNVS137H – MARCH 1999 – REVISED APRIL 2013 www.ti.com APPLICATION HINTS WSON PACKAGE DEVICES The LP2986 is offered in the 8 lead WSON surface mount package to allow for increased power dissipation compared to the SOIC-8 and VSSOP-8. For details on WSON thermal performance as well as mounting and soldering specifications, refer to the WSON MOUNTING section. EXTERNAL CAPACITORS Like any low-dropout regulator, external capacitors are required to assure stability.
PAGE 13
LP2986 www.ti.com SNVS137H – MARCH 1999 – REVISED APRIL 2013 Be warned that the ESR of a ceramic capacitor can be low enough to cause instability: a 2.2 µF ceramic was measured and found to have an ESR of about 15 mΩ. If a ceramic capacitor is to be used on the LP2986 output, a 1Ω resistor should be placed in series with the capacitor to provide a minimum ESR for the regulator.

LP2986 SNVS137H – MARCH 1999 – REVISED APRIL 2013 www.ti.com WSON MOUNTING The LDC08A (Pullback) 8-Lead WSON package requires specific mounting techniques which are detailed in Application Note AN-1187. Referring to the section PCB Design Recommendations in AN-1187 (Page 5), it should be noted that the pad style which should be used with this WSON package is the NSMD (non-solder mask defined) type.

LP2986 www.ti.com SNVS137H – MARCH 1999 – REVISED APRIL 2013 REVERSE INPUT-OUTPUT VOLTAGE The PNP power transistor used as the pass element in the LP2986 has an inherent diode connected between the regulator output and input. During normal operation (where the input voltage is higher than the output) this diode is reverse-biased.
