The LTC1844 Series are low noise VLDO™ (very low dropout) linear regulators designed for low power/portable applications. These regulators can operate from input voltages as low as 1.6V. Typical output noise is only 30µVRMS and typical dropout for the LTC1844-3.3 is just 90mV at the maximum load current of 150mA, reducing to 30mV at 50mA.
The internal P-channel MOSFET pass transistor requires no base current, allowing the device to draw only 35µA during normal operation, independent of the dropout voltage and load current. The quiescent current falls to a negligible 10nA during shutdown.
Other features include high output voltage accuracy, excellent transient response, stability with ultralow ESR ceramic capacitors as small as 1µF, reverse-battery and reverse-current protection, short-circuit and thermal overload protection and output current limiting.
The LTC1844 regulators are available in a low profile (1mm) SOT-23 (ThinSOT™) package.
