L2800

UNISONIC TECHNOLOGIES CO., LTD L2800 LINEAR INTEGRATED CIRCUIT SWITCHING REGULATOR CONTROLLER(LOW VOLTAGE)  DESCRIPTION The UTC L2800 which is incorporating a soft start function and short circuit detection function is a single-channel switching regulator control IC and is made for low voltage applications. Because the device has a low minimum operating voltage of 1.8V, so it is ideal for the power supply of battery-operated electronic equipment.  FEATURES *Wide supply voltage operating range: 1.8V~15V *Low current consumption: Typically 5.5mA in operation,1μA or less in stand-by *High speed operation is possible: Maximum 1MHz *The error amplifier gain is set inside the IC, so peripheral components are minimized. *Incorporates a soft start circuit. *Incorporates a timer-latch type short circuit detection circuit (SCP). *Totem-pole type output with adjustable on/off current (for NPN transistors) *Incorporates a stand-by function.  ORDERING INFORMATION Ordering Number Lead Free Halogen Free L2800L-S08-T L2800G-S08-T L2800L-S08-R L2800G-S08-R L2800L-P08-T L2800G-P08-T L2800L-P08-R L2800G-P08-R Package SOP-8 SOP-8 TSSOP-8 TSSOP-8 SOP-8 TSSOP-8 Packing Tube Tape Reel Tube Tape Reel www.unisonic.com.tw Copyright © 2013 Unisonic Technologies Co., Ltd 1 of 7 QW-R103-030.C L2800  PIN CONFIGURATION LINEAR INTEGRATED CIRCUIT  PIN DESCRIPTION PIN NO. 1 2 3 4 5 6 7 8 SYMBOL -IN SCP VCC BR/CTL OUT GND OSC FB I/O I I O O DESCRIPTION Error amplifier inverting...
