The US1050-33 product is a low dropout three terminal fixed 3.3V output regulator with minimum of 5A output current capability. This product is specifically designed to provide well regulated supply for low voltage IC applications requiring 3.3V output. The US 1050-33 is guaranteed to have <1.3V drop out at full load current making it ideal to provide well regulated output with supply voltage as low as 4.6V input.
