The SY6321C is a low-dropout (LDO) regulator capable of sourcing 1 A with only 200mV of dropout.
The SY6321C output is adjustable from 0.8V to 5.2V with external resistors. The SY6321C wide input-voltage range supports operation as low as 1.65V and up to 6.5V.
With 2% output voltage accuracy (over line, load, and temperature) and soft-start capabilities to reduce inrush current, the SY6321C is ideal for powering sensitive analog low-voltage devices [such as voltage-controlled oscillators (VCOs), analog-to-digital converters (ADCs), digital-to-analog converters (DACs), high-end processors, and field programmable gate arrays (FPGAs)].
The SY6321C is available in a compact DFN 2.5×2.5-10 package.
