The SK6054S5-12 is a Linear Voltage Regulator (LDO) manufactured by Suntek. It is a surface mount device in a SOT23-5 package and is RoHS complaint. The LDO is a three-terminal low dropout voltage regulator that maintains a stable output voltage with a minimum amount of input-output voltage differential. It has a fast turn-on time, low noise, and a wide operating temperature range, making it an ideal choice for portable appliances, computers, networking and communications equipment, and automotive applications. The SK6054S5-12 has a fixed output voltage of 5V and provides a maximum output current of up to 100mA. It has low ground current of 18µA and low quiescent current of 40µA. It also offers over current, thermal, and short circuit protection, making it an efficient and reliable part for a variety of applications.
