ILC7280
Advance Micropower Dual 150mA CMOS RF LDO Regulators with 75dB Ripple Rejection General Description 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 130A at 1mA load, and 135A at 150mA load. Ripple Rejection: 55dB at 1kHz and 60dB at 100kHz. Shutdown mode: Less than 0.5A quiescent current in shutdown mode. Small package: MSOP-8 Small capacitor: Requires only a 0.47F external capacitor on the regulator output. Precision output: Output voltage trimmed to 1% accuracy. Output Noise: 80VRMS, optional noise bypass capacitor at pin 3 will further reduce noise on VOUTA/B Voltage Pairings available: 3.0/3.0V, 3.0/2.8V, 3.0/2.5V, 2.8/2.8V Features Guaranteed 150mA output per regulator Ultra low 150mV dropout at 150mA 1% output voltage accuracy Requires only 0.47F output capacitor Only 150A ground current at 150mA load 60dB ripple rejection at 1kHz (COUT = 0.47F) 80VRMS noise at BW = 300Hz to 50kHz Excellent line and load transient response Over current / over te……
