1 / 7 page UNISONIC TECHNOLOGIES CO., LTD LC1111 Advance LINEAR INTEGRATED CIRCUIT www.unisonic.com.tw 1 of 7 Copyright © 2015 Unisonic Technologies Co., Ltd QW-R102-072.a 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 pulling the EN under 0.4 disables output. FEATURES * 4.5V~13.5V supply voltage range * 0.8V (±2%) voltage reference (temperature and process) * Power-On-Reset monitoring on VCC * Fast transient response * Programmable soft-start * Enable control function * Low shutdown current * Under-Voltage protection * Two versions of IC available: UVP activated after VOUT is ready SOT-26 4 5 3 2 1 6 ORDERING INFORMATION Ordering Number Package Packing LC1111G-AG6-R SOT-26 Tape Reel |
