SUL6018S5-18

SUL6018 1.3uA, High PSRR, 350mA Low-Dropout Linear Regulator FUNCTIONAL DESCRIPTION MAIN FEATURES The SUL6018 is an ultra-small, ultra-low quiescent current low-dropout linear regulator (LDO) that can source 350mA with excellent transient performance. ⚫ ⚫ ⚫ ⚫ The SUL6018, with an ultra-low IQ of 1.3μA, is designed specifically for applications where very-low quiescent current is a critical parameter. This device maintains low IQ consumption even in dropout mode to further increase the battery life. ⚫ ⚫ ⚫ ⚫ ⚫ ⚫ The feature of 1.3μA low quiescent current and 0.05μA shutdown current are ideal for the battery application with long service life. The other features include current limit function, over temperature protection and output discharge function. Input Voltage Range: 1.2V to 5.5V Ultra Low IQ: 1.3μA High PSRR = 85dB @1KHz Output Voltage Range: - Adjustable Mode: 0.8V to 4.5V - Fixed Mode: 0.8V~4.5V, 0.05V step. High Output Accuracy: ±1% Ultra Low Dropout Voltage: 150mV @ 350mA when VOUT ≥ 3V Low Noise: 30 μVrms Current Limit Protection Over Temperature Protection Output Active Discharge Function APPLICATIONS The SUL6018 is available SOT-23-5 and DFN-1x1-4L Packages. Standard products are Pb-free and Halogen-free. ⚫ ⚫ Portable, Battery Powered Equipment Ultra Low Power Microcontrollers ⚫ Notebook Computers ORDERING INFORMATION PART NO PACAKGE TEMPERATURE TAPE & REEL SUL6018S5-XX Note SOT23-5L -40 ~ +85℃ 3000/REEL DFN1x1-4L -40 ~ +85℃ 10000/REEL SUL6018D4-XX Note Note:XX indicates Vout.
