TPS7A47: LOW NOISE LDO

Guru 13485 points
Part Number: TPS7A47
Other Parts Discussed in Thread: TPS7A33

Looking for right/recommended LDOs:

1)Positive LDO,

  • Input voltage 9-12Vdc.
  • I max <1A.
  • PSSR>70db.
  • Adjustable V-out.
  • Good thermal resistance.
  • Small size.

 

 

2)Negative LDO,

The input voltage is  ~-5VDC, all other demands are the same as the positive ldo.

 

I found   the  TPS7A4700, TPS7A4701 and TI_tps7a33.
