Hi Waqar,
For Vout of 0.8V to 5V+:
The TPS7A83/4/5 and TPS7A87/8/9 family of devices are targeted at low-noise, high PSRR rails for Iout = 500mA to 4A.
Other parts to look are the TPS717 (150 mA), TPS734/735 (250mA/500mA), and the LP5907/10/12 (250…
Other Parts Discussed in Thread: TPS709 , TPS732 , TPS734 , TPS737 Hi all. Please see the circuit using TPS78001. The input source of this circuit is the PV, and it fluctuates between 0V~5V. Can I use the TPS78001 in this case? If I can't use the TPS78001 in…
Hi Kevin,
I hope that things work out - I am always nervous when it comes to these noise problems.
Your plans look good. I only mentioned the TPS734 so that you have two options to try.
I would rather use the ferrite with the additional dc resistance…
Other Parts Discussed in Thread: TPS734 , TPS732 Hi,
I'm using the 3.0V out of the 3201 to drive an ECG circuit AND a pulse oximeter circuit. I believe the switching noise of the pulse oximeter circuit is coupled through the common power. I want to do whatever…
