LC1118 Dual 1A Low Dropout Regulator DESCRIPTION FEATURES LC1118 is a dual channel low-dropout regulator that Dual channel output with each individual delivers a maximum current of 1A for each output can be either fixed output version or individual output. Typical dropout voltage at 1A adjustable version. load current is 1.3V. Each individual output voltage Maximum output current for each channel is 1A can be set independently as fixed voltage (e.g. 1.2V, Range of operation input voltage: Max 12V 1.8V, 2.5V, 3.3V, 5V) or adjustable output which can Standby current of each output: 2mA (typ.) provide an output voltage from 1.25 to 12V with Line regulation: 0.1%/V (typ.) two external resistors. The output accuracy of each Load regulation: 10mV (typ.) channel is set within 2% by trimming. Environment temperature: -20 C~85 C Compatible with tantalum capacitor, LC1118 offers thermal shut down and current limit electrolytic capacitor and MLCC. functions to ensure reliability of device and power system. APPLICATIONS Package input/output pin configuration can be Power management for computer mother customized on demand (i.e. both output can share board, graphic card one input to save one input capacitor and LCD monitor and LCD TV corresponding PCB real estate). DVD decoder board ADSL modem LC1118 is available in lead (Pb)-free ESOP-8(with Post regulators for switching supplies exposed pad for heat dissipation) package.
