| IP1117/IP1117-18/IP1117-25/IP1117-33/IP1117-50 LDO Regulator with Adjustable and Fixed 1.8V, 2.5V,3.3V,5.0V DESCRIPTION The IP1117 is a series of low dropout voltage regulators which can provide up to 1.0A of output current. The IP1117 is available in four fixed voltages, 1.8V,2.5V,3.3V and 5.0V. In addition, it is also available in adjustable version. On chip precision trimming adjusts the reference/output voltage to within 2%. Current limit is also trimmed to ensure specified output current and controlled short-circuit current The IP1117 series is available in SOT-223 power packages. SOT-223 FEATURES - Adjustable and Fixed of 1.8V, 2.5V, 3.3V,5.0V - Space saving SMD types of SOT-223 - 1.0A Output Current capability - 1.1V drop-out voltage - Foldback current limiting - Thermal protection - Over current protection ORDERING INFORMATION Device IP1117/ IP1117L IP1117-18/ IP1117L-18 IP1117-25/ IP1117L-25 IP1117-33/ IP1117L-33 IP1117-50/ IP1117L-50 L means Lead-free Package SOT-223 SOT-223 SOT-223 SOT-223 SOT-223 -35 OC ~ +125O C Operating Temp APPLICATIONS - Post Regulator for Switching DC/DC Converter - CD Media - Battery Charger - Battery Powered Equipments TYPICAL APPLICATION CIRCUITS Jan. 2005 (Rev.5) www.interpionsemi.com -1- IP1117/IP1117-18/IP1117-25/IP1117-33/IP1117-50 LDO Regulator with Adjustable and Fixed 1.8V, 2.5V,3.3V,5.0V PIN CONNECTIONS PIN DESCRIPTIONS NO 1 2 3 SYMBOL ADJ/GND OUT IN I/O O I DESCRIPTION Adjustable or Power Ground Output Input ABSOLUTE MAXIMUM RATINGS Parameter Input Voltage Junction Temperature Storage Temperature Symbol Vinmax Tj Tstg Value 18 -35 ~ +125 -55 ~ +150 Units V O C C O Absolute Maximum Safe Operating Area Output Current(A) 1.2 1.0 0.8 0.6 0.4 0.2 0 2 4 6 8 10 12 14 16 18 20 SOA Vin - Vout (V) -2- Jan. 2005 (Rev.5) www.interpionsemi.com IP1117/IP1117-18/IP1117-25/IP1117-33/IP1117-50 LDO Regulator with Adjustable and Fixed 1.8V, 2.5V,3.3V,5.0V Electrical Characteristics ( Vin= 5V, Co=10uF, Ta = 25O C, unless otherwise specified.)
