ILC7280

Impala Linear Corporation ILC7280 Advance Micropower Dual 150mA CMOS RF LDO™ Regulators with 75dB Ripple Rejection General Description Features The ILC7280 is two independent 150mA low dropout (LDO) voltage regulators in an 8-pin MSOP package. Each regulator output is independently short circuit protected and has independent enable lines. The device offers a unique combination of low dropout voltage and low quiescent current of CMOS as well as the low noise and high ripple rejection characteristics of bipolar LDO regulators. Moreover, only one input capacitor is required. Dropout Voltage: Typically 150mV at 150mA load, and 1mV at 1mA load. Ground pin current: Typically 130µA at 1mA load, and 135µA at 150mA load. Ripple Rejection: 55dB at 1kHz and 60dB at 100kHz. Shutdown mode: Less than 0.5µA quiescent current in shutdown mode. Small package: MSOP-8 Small capacitor: Requires only a 0.47µF external capacitor on the regulator output. Precision output: Output voltage trimmed to 1...
