LP2985LV Datasheet | National Semiconductor

Description The LP2985LV is a 150 m A, fixed-output voltage regulator designed to providehigh performance and low noise in appli- cations requiring output voltages ≤ 2.0V. Using an optimized VIP® (Vertically Integrated PNP) process, the LP2985LV delivers unequalled performance in all specifications critical to battery-powered designs: Ground Pin Current: Typically 825 µA @ 150 m A load, and 75 µA @ 1 m A load. Enhanced Stability: The LP2985LV is stable with output capacitor 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: micro SMD package uses absolute minimum board space. Precision Output: 1% tolerance output voltages available (A grade). Low Noise: By adding a 10 n F bypass capacitor, output noise can be reduced to 30 µV (typical).

Basic Application Circuit   - ON/OFF input must be actively terminated. Tie to VIN if this function is not to be used.  - - Minimum capacitance is shown to ensure stability (may be increased without limit). Ceramic capacitor required for output (see Application Hints). - - - Reduces output noise (may be omitted if application is...
