LT3029IDE#PBF

LT3029 is a dual, micropower, low noise, low dropout linear regulator. This device operates either with a common input supply or independent input supplies for each channel, over an input voltage range of 1.8V to 20V. With an external 10nF bypass capacitor, output noise is only 20µVRMS over a 10Hz to 100KHz bandwidth. This device optimizes stability and transient response with low ESR ceramic output capacitors, requiring a minimum of only 3.3µF. The regulator does not require the addition of ESR, as is common with other regulators. Internal circuitry provides reverse-battery protection, reverse-current protection, current limiting with foldback and thermal shutdown. The device is available as an adjustable output voltage device with a 1.215V reference voltage. It is widely used in application such as general purpose linear regulator, battery-powered systems, microprocessor core/logic supplies, post regulator for switching supplies, tracking/sequencing power supplies etc.

• Output current is 500mA per channel
• Low dropout voltage is 0.11V typical at (ILOAD = 10mA)
• Low quiescent current is 55µA typical
• Wide input voltage range is 1.8V to 20V (common or independent input supply)
• Very low quiescent current in shutdown is 1µA maximum
