S1117

PRELIMINARY S1117 Features ◆ Adjustable and Fixed of 1.8V, 2.5V, 2.85V, 3.3V, 5V ◆ Space saving SMD types of SOT-223 and D-Pak(TO-252) ◆ 1.1V Drop-out Voltage ◆ 1.0A Output Current ◆ Current Limiting and Thermal protection ◆ Over Current Protection. ◆ Ouput trimmed to 2% Tolerance ◆ Fast Transient Response LDO Linear Regulator Symbol General Description The IP1117 is a series of low dropout voltage regulators which can provide up to 1A of output current. The IP1117 is available in four fixed voltages, 2.5V, 2.85V, 3.3V and 5.0V. Additonally it is also available in adjustable version. On chip precision trimming adjusts the refernce/ output voltage to within ± 2%. Current limit is also trimmed to ensure specified output current and controlled short-circuit current. The IP11117 series is available in SOT-223 and DPAK power packages. A minimum of 10uF tantalum capacitor is required at the output to improve the transient response and stability. DPAK SOT-223 Applications ◆ 2.85V Model for SCSI-2 Active Termination ◆ Post Regulator for Sitching DC/DC Converter ◆ High Efficiency Linear Regulator ◆ Battery Chargers ◆ PC Add on Card Absolute Maximum Ratings Parameter Input Voltage Junction Temperature Storage Temperature Symbol VIN(MAX) TJ TSTG Value 18 -25°C ~ +125°C -55°C ~ +150°C Units V °C °C Electrical Characteristics ( Vin = 5V, Co = 10uF, Ta = 25°C, unless otherwise specified) Parameter Symbol Test Condition Reference Voltage Vref S1117 Only 1.5V < (VIN -VOUT) < 7V, IO = 10mA S1117-1.8 10mA < IOUT < 1A, 3.8V < VIN < 10V S1117-2.5 10mA < IOUT < 1A, 4.0V < VIN < 10V Output Voltage Vout S1117-2.85 10mA < IOUT < 1A, 4.25V < VIN < 10V S1117-3.3 10mA < IOUT < 1A, 4.75V < VIN < 10V S1117-5.0 10mA < IOUT< 1A, 6.5V < VIN
