The SK6018CD4-28 with DFN1x1-4 Linear Voltage Regulators (LDO) ROHS is an electronic component manufactured by Suntek. It is a low-dropout (LDO) regulator with an output current of up to 250mA and an input voltage range of 2.5V to 6V. It features an operating temperature range from -40°C to 125°C, low dropout voltage and high accuracy voltage regulation. The chip is RoHS compliant and is available in both commercial and industrial grades. It also has an internal reverse current protection circuit to prevent accidental reverse connections. With its small package size, the SK6018CD4-28 is ideal for space-constrained applications.
