... Because there is no base drive, the regulator is capable of providing high current surges while remaining in regulation. This is shown in the high peak current of 500mA which allows for the ILC7082 to be used in systems that require short burst mode operation. (408) 574-3939 www.impalalinear.com ...

... SOT-23 Ultra Low Noise CMOS RF-LDO™ Regulator ELECTRICAL CHARACTERISTICS ILC7082AIM5 (continued) Shutdown (ON/OFF) Operation The ILC7082 output can be turned off by applying 0.4V or less to the device’s ON/OFF pin (pin 3). In shutdown mode, the ILC7082 draws less than 1mA quiescent current. The output of the ILC7081 is enabled by applying 1 ...

... ESR output capacitor for superior load transient response. The ILC7082 is stable with no load. Noise Bypass Capacitor In low noise applications, the self noise of the ILC7082 can be decreased further by connecting a capacitor from the noise bypass pin (pin 4) to ground (pin 2). The noise bypass ...

... LDO. Particularly the accumulation of current flows in the ground plane can develop significant voltages unless care is taken. With a degree of care, the ILC7082 will yield outstanding performance. Printed Circuit Board Layout Guidelines As was mentioned in the previous section, to take full advantage of any high performance LDO regulator requires paying careful attention to grounding and printed circuit board (PCB) layout ...
