The SK6215T3B-33 is a Linear Voltage Regulator (LDO) with an SOT-89 package manufactured by Suntek. This component is a low-dropout-voltage regulator made in compliance with the RoHS (Restriction of Hazardous Substances), which restricts the use of lead, mercury, cadmium, hexavalent chromium, and other hazardous materials in electronic products. It has an input voltage of 2.7V to 6V and an output voltage of 1.2V to 5V, with a maximum output current of 700mA. It also features a fast transient response and low dropout voltage, making it ideal for input/output voltage regulation in a wide variety of low-voltage applications. Additionally, this LDO is able to maintain a stable output voltage and reduce output noise in low-voltage applications and offers excellent load and line regulation.
