ILC7081 Datasheet | Fairchild Semiconductor

Features - Ultra low 1m V dropout per 1m A load - 1% output voltage accuracy - Uses low ESR ceramic output capacitor to minimize noise and output ripple - Only 100µA ground current at 100m A load - Ripple rejection up to 85d B at 1k Hz, 60d B at 1MHz - Less than 80µVRMS noise at BW = 100Hz to 100k Hz - Excellent line and load transient response - Over current / over temperature protection - Guaranteed up to 80/150m A output current - Industry standard five lead SOT-23 package - Fixed 2.5V, 2.6V, 2.7V, 2.8V, 2.85V, 2.9V, 3.0, 3.1V, 3.3V, 3.6V, 4.7V, 5.0V and adjustable output (ILC7081 only) voltage options - Metal mask option available for custom voltages between 2.5 to 5.1V Description The ILC7080/81 are 50 or 100m A low dropout (LDO) voltage regulators designed to provide a high performance solution to low power systems. The devices offer a typical bination 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 munications design; Low noise, low dropout, small size, high peak current, high noise immunity. The ILC7080/81 are designed to make use of low cost ceramic capacitors while outperforming other devices that require tantalum capacitors.
