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 of the ILC7281 can sink 2mA, the monitor draws only 1A in normal operation. Additionally, a built-in hysteresis of 5% of detect voltage simplifies system design.
