LP2985LV Datasheet, PDF (3/18 Pages) National Semiconductor (TI) – Micropower 150 mA Low-Noise Low-Dropout Regulator in SOT-23 and micro SMD packages for Applications

Basic Application Circuit
10129502
  *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).

Note: The actual physical placement of the package marking will vary from part
to part. Package marking contains date code and lot traceability information, and
will vary considerably. Package marking does not correlate to device type.
