L1117D-3.3

NIKO-SEM 1A Fixed and Adjustable Low Dropout Linear Regulator (LDO) L1117 Series SOT-223, TO-252, TO-220,TO-263 GENERAL DESCRIPTION The L1117 Series are positive and low dropout three-terminal voltage regulators with 1A output current capability. These devices are designed for use in low voltage applications that offers lower dropout voltage and faster transient response. These devices are fully protected against over current faults, over temperature operation, reversed input polarity, reversed lead insertion, transient voltage spike …etc. On-Chips trimming the reference voltage to 2% and features the low dropout of maximum 1.45 volts. The L1117 Series regulators offer fixed and adjustable voltage options available in the popular industry standard SOT-223, TO-220, TO-252 and TO-263 packages. FEATURES Fixed 2.5V, 2.85V, 3.3V, 5V or adjustable output voltage Low dropout voltage: 1.2V typical at up to 1A Low ground current Fast transient response Current & thermal limiting Line regulation: 0.5% typical Load regulation: 0.5% typical SOT-223,TO-220,TO-252,TO-263 package APPLICATIONS 2.85V active SCSI terminators 8-15V to 5V linear regulators 5V to 2.5V or 3.3V linear regulators Low voltage micro-controllers Battery Chargers Motherboard clock supplies Post regulator for switching supplies Micro-controllers ABSOLUTE MAXIMUM RATINGS Maximum Supply Voltage Power Dissipation Thermal Resistance Junction to Case, θJC Thermal Resistance Junction to Ambient, θJA SOT-223 TO-252 TO-220 TO-263 15V* Internally Limited 16 °C/W Operating Junction Temperature Range Storage Temperature Range Lead Temperature (Soldering, 10 Seconds) 0 to 125 °C -40 to 150 °C 260 °C 158 °C/W 70 °C/W 50 °C/W 60 °C/W * W hen considering short circuits to ground, the maximum input-to-output differential voltage shall not be allowed greater than approximate 2~3V at values of supply voltage in excess of 10V, continuous short-circuits can exceed the power dissipation ratings and cause eventual destruction. 1 JUL-27-2001 NIKO-SEM 1A Fixed and Adjustable Low Dropout Linear Regulator (LDO) L1117 Series SOT-223, TO-252, TO-220,TO-263 ELECTRICAL CHARACTERISTICS for ADJUSTABLE(Unless otherwise specified, TA = 25°C) Parameter Symbol Test Conditions Typical 1.25V VO 1.2V 0.5% 0.5% 10mA 55µA 1.2A 0.003% of VOUT 72dB 100µA 1.1A (Min) Limits 1.23VMin 1.27VMax 0.98VO(Min) 1.02VO(Max) 1.45V 2% 2.5% Reference Voltage (Adjustable version) VREF VIN = 5V, IOUT = 10mA Output Voltage VO VIN = 5V, IOUT = 10mA (Fixed version) Dropout Voltage VD ΔVREF = 1%, IOUT = 1A Line Regulation REG(LINE) (VOUT + 1.5V) ≤ VIN ≤ 15V, IOUT = 10mA Load Regulation REG(LOAD) (VIN -VOUT) = 2V, 10mA ≤ IOUT ≤ 1A Minimum Load Current IO IADJ ICL VN RA 1.5V ≤ (VIN -VOUT) ≤ 5.75V VIN -
