PT2399 echo/delay chip used in many DIY and commercial pedals. The PT2399 is in a DIP 16 package. Minimal external components are required for use and delay time is set with resistance.

"The PT2399 is a single chip echo processor IC utilizing CMOS technology. Which accept analog audio input signal, a high sample rate ADC transfer the analog signal into a bit stream then storage to internal 44Kbit RAM, after processing the bit stream will de-modulate by DAC and lowpass filter. Overall delay time is determined by internal VCO clock frequency, and user can easy to change the VCO frequency by changing the external resistance. The PT2399 performs low distortion (THD<-90dBV) characteristic for audio purpose, and pin arrangement and application circuit are optimized for easy PCB layout and cost saving advantage." – Princeton Technology Corp.

5V is the recommended supply voltage for the PT2399. Need a 5V regulator? See P-QMC78L05 and P-QMC7805.
