LP2978_09 Datasheet, PDF (2/8 Pages) National Semiconductor (TI) – Micropower SOT, 50 mA Low-Noise Ultra Low-Dropout Regulator Designed for Use with Very Low ESR Output Capacitors

Basic Application Circuit
10093502
  *ON/OFF input must be actively terminated. Tie to V_IN 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 not noise critical). Use ceramic or film type with very low leakage current (see Application Hints).
