1 / 16 page ILC7080/81 50/100mA SOT-23 CMOS RF LDO™ Regulators Impala Linear Corporation Impala Linear Corporation 1 (408) 574-3939 www.impalalinear.com Sept. 1998 ILC7080/81 1.1 The ILC7080/81 are 50 or 100mA low dropout (LDO) volt- age regulators designed to provide a high performance solution to low power systems. The devices offer a typical combination of low dropout and low quiescent current expected of CMOS parts, while uniquely providing the low noise and high ripple rejection characteristics usually only associated with bipolar LDO regulators. The devices have been optimized to meet the needs of modern wireless communications design; Low noise, low dropout, small size, high peak current, high noise immuni- ty. The ILC7080/81 are designed to make use of low cost ceramic capacitors while outperforming other devices that require tantalum capacitors. General Description Features • Ultra low 1mV dropout per 1mA load • 1% output voltage accuracy • Uses low ESR ceramic output capacitor to minimize noise and output ripple • Only 100µA ground current at 100mA load • Ripple rejection up to 85dB at 1kHz, 60dB at 1MHz • Less than 80µVRMS noise at BW = 100Hz to 100kHz • Excellent line and load transient response • Over current / over temperature protection • Guaranteed up to 80/150mA output current • Industry standard five lead SOT-23 package • Fixed 2.85V, 3.0V, 3.3V, 3.6V, 4.7V, 5.0V and adjustable output voltage options • Metal mask option available for custom voltages between 2.5 to 10V • Cellular phones • Wireless communicators • PDAs / palmtops / organizers • Battery powered portable electronics Applications Typical Circuit ILC7080 ILC7081 V OUT V IN C OUT C NOISE SOT23-5 12 3 4 5 ON OFF Ordering Information (TA = -40°C to +85°C) ILC7080AIM5-xx 50mA, fixed voltage ILC7080AIM5-ADJ 50mA adjustable voltage ILC7081AIM5-xx 100mA, fixed voltage ILC7081AIM5-ADJ 100mA, adjustable voltage Note: Fixed voltage options are defined by 2-digit code as shown in the package markings information section of the datasheet. |
