Dual low-dropout voltage regulator ideal for powering sensitive analog low-voltage devices

Texas Instruments TPS7A87 Dual Low-Dropout Voltage Regulator, available from Mouser, is capable of sourcing 500mA per channel with 100mV of maximum dropout. This device provides the flexibility of two independent LDOs and approximately 30% smaller solution size than two single-channel LDOs. Each output is adjustable with external resistors from 0.8V to 5.2V. The wide input voltage range of the device supports operation as low as 1.4V and up to 6.5V. With 1% output voltage accuracy and soft-start capabilities to reduce in-rush current, the device is ideal for powering sensitive analog low-voltage devices. This device is designed to power noise-sensitive components such as those found in instrumentation, medical, video, professional audio, test and measurement, and high-speed communication applications. The very low 3.8µVRMS output noise and wideband PSRR (40dB at 1MHz) minimises phase noise and clock jitter.
