The TLV1117 is a versatile and high-performance, linear regulator with a wide temperature range and tight line and load regulation operation. An output capacitor is required to further improve transient response and stability. For the adjustable option, the ADJ pin can also be bypassed to achieve very-high, ripple-rejection ratios. The TLV1117 is versatile in the device applications, including being used as a post regulator for DC/DC converters, battery chargers, and microprocessor supplies.
