The LP2978 is a 50 mA, fixed-output voltage regulator designed to provide ultra low-dropout and low noise in battery powered applications.

Using an optimized VIP™ (Vertically Integrated PNP) process, the LP2978 delivers unequalled performance in all specifications critical to battery-powered designs:

Dropout Voltage: Typically 120 mV @ 50 mAload, and 7 mV @ 1 mA load.

Ground Pin Current: Typically 350 A @ 50 mA load, and 75 A @ 1 mA load.

Enhanced Stability: The LP2978 is stable with output capacitor ESR as low as 5 mW, which allows the use of ceramic capacitors on the output.

Sleep Mode: Less than 1 A quiescent current when ON/OFF pin is pulled low.

Smallest Possible Size: SOT-23 package uses 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 V (typical).
