L1136

UNISONIC TECHNOLOGIES CO., LTD L1136 Preliminary CMOS IC HIGH RIPPLE-REJECTION LOW DROPOUT HIGH OUTPUT CURRENT CMOS VOLTAGE REGULATOR DESCRIPTION The UTC L1136 is an extremely low dropout regulator providing designers with low current dissipation, high output voltage accuracy and it is developed based on CMOS technology. The internal transistor with low-resistance provides small dropout voltage and the large output current. Various capacitors, as well as small ceramic capacitors, can be used for this IC more than for the conventional regulator ICs which have CMOS technology. The ON/OFF circuit can guarantee longer sure the battery life. The over-current protection circuit is designed to protect the device from being damaged because of load current while exceeding the capacitance of output transistor. The thermal shutdown protection circuit protects against heat and the rush current control protection circuit and limits the excessive rush current during start-up. The UTC L1136 is universally suitable for power supply of battery-powered devices, power supply of TV, notebook PCs and home electric appliances, and constant-voltage power supply of portable equipment.
