简  介: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 1A 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 20A at 1mA load, and 30A at 150mA load. Ripple rejection: 75dB at 1kHz and 60dB at 100kHz. Shutdown mode: Less than 0.5A quiescent current in shutdown mode. Small package: 8-pin MSOP. Small capacitor: Requires only a 0.47F external cpacitor on the regulator output. Precision output: Output voltage trimmed to 1% accuracy. Features Guaranteed 150mA output per regulator Ultra low 150mV dropout at 150mA 1% output voltage accuracy Built-in hysteresis of 5% of detection voltage Requires only 0.47F output c……
