2 / 10 page ![]() SCD8691 Rev H 11/12/13 Aeroflex Plainview 2 ABSOLUTE MAXIMUM RATINGS PARAMETER RANGE UNITS Operating (Junction) Temperature Range -55 to +150 °C Lead Temperature (soldering, 10 sec) 300 °C Storage Temperature Range -65 to +150 °C VBIAS, VIN 7V Thermal Resistance (Junction to case JC)1 °C/W Power 25 1/W 1/ Based on pass transistor limitations of (VIN - VO) x IO and JC < 1°C/W with 25°C max TJ rise and TC = +125°C. NOTICE: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only; functional operation beyond the “Operation Conditions” is not recommended and extended exposure beyond the “Operation Conditions” may effect device reliability. RECOMMENDED OPERATING CONDITIONS PARAMETER RANGE UNITS Output Voltage Range 1.0 to 3.3 VDC Case Operating Temperature Range -55 to +125 °C Output Current 0 to 7.5 A VBIAS 3.3 to 5.5 1/VDC VIN 1.8 to 5.5 2/VDC 1/ VBIAS must maintain a level equal or above VIN but not fall below 3.3V 2/ Depending upon VOUT setting.
