ILC7281

Impala Linear Corporation ILC7281 Advance Micropower Dual 150mA CMOS RF LDO™ Regulators with Power Supply Reset Monitor General Description The ILC7281 provides two independant 150mA low dropout (LDO) voltage regulators and power supply reset monitor in an 8-pin MSOP package. Each regulator output is independantly short circuit protected and has independant shutdown. The device offers a unique combination of low dropout voltage and low quiescent current of CMOS and low noise and high ripple rejection characteristics of bipolar LDO regulators. Moreover, only one input capacitor is required. The power supply reset monitor is available in a ±1% accurate trip voltage to fit most microprocessor applications. Even though its output can sink 2mA, the monitor draws only 1µA in normal operation. Additionally, a built-in hysteresis of 5% of detect voltage simplifies system design. Dropout Voltage: Typically 150mV at 150mA load, and 1mV at 1mA load. Ground pin current: Typically 20µA at 1mA...
