LP2981/LP2985/LP2985LV

Ultra-low dropout regulator with shutdown

Features

Target Applications

• Wide V_INrange: 2.2 V to 16 V

• Stable with ceramic capacitors (LP2985, LP2985LV)

• Notebooks, desktop PCs

• PC peripheral cards

• Very low dropout voltage, typically:

• 70 mV at 25 mA

• PDAs, mobile phones, palmtops

• Telecommunications/modems

• Media players

• Digital still cameras, VCRs, camcorders

• Storage card and system

• Industrial/automotive

• 200 mV at 100 mA

• 280 mV at 150 mA

• Output tolerance (LP2981/LP2985):

• 0.75%/1% (A grade)

• 1.25%/1.5% (standard grade)

• Low noise: 30 µV (300 Hz to 50 kHz) (LP2985, LP2985LV)

• Wide operating temperature range (T_j): –40°C to 125°C

• Low quiescent current in shutdown: 0.01 µA (typ)

• Overcurrent and thermal protection
