Description

Description
The LP2992 is a 250-mA, fixed-output voltage regulator designed to provide ultra-low dropout and low noise in battery-powered applications.
Using an optimized vertically integrated PNP (VIP) process, the LP2992 delivers unequaled performance in all specifications critical to battery-powered designs:
• Dropout voltage: Typically 450 mV at 250-mA
   load, and 5 mV at 1-mA load.
• Ground pin current: Typically 1500 µA at 250-mA
   load, and 75 µA at 1-mA load.
• Enhanced stability: The LP2992 is stable with
   output capacitor equivalent series resistance
   (ESR) as low as 5 mΩ, which allows the use of
   ceramic capacitors on the output.
• Sleep mode: Less than 1-µA quiescent current
   when ON/OFF pin is pulled low.
• Smallest possible size: SOT-23 and WSON
   packages use absolute minimum board space.
• Precision output: 1% tolerance output voltages
   available (A grade).
• Low noise: By adding a 10-nF bypass capacitor,
   output noise can be reduced to 30 µV (typical).
• Multiple voltage options, from 1.5 V to 5 V, are
   available as standard products. Consult factory for
   custom voltages.
