LT3030MPFE#PBF

LT3030MPFE#PBF is a dual, micropower, low-noise, low-dropout linear regulator. This device operates with either common or independent input supplies for each channel, spanning a 1.7V to 20V input voltage range. Output 1 supplies 750mA, while output 2 supplies 250mA, both with a typical dropout voltage of 300mV. When equipped with an external 10nF bypass capacitor, output noise is a mere 20μVRMS over a 10Hz to 100KHz bandwidth. Designed for battery-powered systems, its low 120μA/75μA quiescent current makes it an ideal choice. In shutdown mode, the quiescent current drops to less than 1μA. Shutdown control is independent for each channel, with precision logic threshold enabling voltage lockout functionality. Applications include general-purpose linear regulation, battery-powered systems, microprocessor core/logic supplies, post regulators for switching supplies, and tracking/sequencing power supplies.

• Wide input voltage range from 1.7V to 20V, PWRGD flag for each output
• Current limit with foldback and thermal shutdown
• Reverse battery and reverse output-to-input protection
• Precision threshold for shutdown logic or UVLO function
• Stable with ceramic, tantalum or aluminium electrolytic capacitors
• GND pin current (output 1) is 120μA typical at (ILOAD = 0mA)
• Output voltage noise is 20μVRMS typical at (COUT = 10μF, CBYP = 10nF, ILOAD = full current)
• Quiescent current in shutdown (per channel) is 0.3μA typ at (VIN = 20V, VSHDN1 = 0V, VSHDN2 = 0V)
• Operating junction temperature range from -55°C to 150°C
• 20-lead plastic TSSOP package
