Product Overview

The LTC3025IDC#PBF is a 300mA micropower very low dropout (VLDO) Linear Regulator operates from input voltages as low as 0.9V. The device is capable of supplying 300mA of output current with a typical dropout voltage of only 45mV. A BIAS supply is required to run the internal reference and LDO circuitry while output current comes directly from the IN supply for high efficiency regulation. The low 0.4V internal reference voltage allows the LTC3025 output to be programmed too much lower voltages than available in common LDOs (range of 0.4 to 3.6V). The output voltage is programmed via two ultra small SMD resistors. The LTC3025's low quiescent current makes it an ideal choice for use in battery-powered systems. For 3-cell NiMH and single cell Li-ion applications, the BIAS voltage can be supplied directly from the battery while the input can come from a high efficiency buck regulator, providing a high efficiency, low noise output.
