LC1111

UNISONIC TECHNOLOGIES CO., LTD LC1111 Advance LINEAR INTEGRATED CIRCUIT LOW DROPOUT LINEAR REGULATOR CONTROLLER  DESCRIPTION The UTC LC1111 is a low dropout linear regulator controller for applications requiring high-current and ultra low dropout voltages. The use of an external N-Channel MOSFET and provide an adjustable output by using an external resistive divider. An extremely accurate 0.8V (±2%) reference allows the implementation of sub 1 V voltage supplies. The reference is guaranteed over the complete supply and temperature ranges. The UTC LC1111 integrates various functions. For example, a Power-On-Reset (POR) circuit monitors VCC supply voltage to prevent wrong operations; the function of Under-Voltage Protection (UVP) protects the device from short circuit condition. The soft-start of output voltage is adjustable by the external capacitor on SS pin. Moreover, the UTC LC1111 can be enabled by other power system; namely, holding the EN above 1.6V enables output and pul...
