ILC7280CS-3025 Datasheet PDF - Impala Linear Corporation

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.

FEATUREs
• Guaranteed 150mA output per regulator
• Ultra low 150mV dropout at 150mA
• 1% output voltage accuracy
• Requires only 0.47µF output capacitor
• Only 150µA ground current at 150mA load
• 60dB ripple rejection at 1kHz (COUT = 0.47µF)
• 80µVRMS noise at BW = 300Hz to 50kHz
