Description

General part information

LTC3025-1LTC3025-2LTC3025-3LTC3025-4 Series

The LTC3025-X is a micropower, VLDO™(very low dropout) linear regulator which operates from input voltages as low as 0.9V. The device is capable of supplying 500mA of output current with a typical dropout voltage of only 85mV. 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 LTC3025-1 features an adjustable output with a low 0.4V reference while the LTC3025-2, LTC3025-3, and LTC3025-4 have fixed 1.2V, 1.5V and 1.8V output voltages respectively.The LTC3025-X’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.Other features include high output voltage accuracy, excellent transient response, stability with ultralow ESR ceramic capacitors as small as 1μF, short-circuit and thermal overload protection and output current limiting. The LTC3025-X is available in a tiny, low profile (0.75mm) 6-lead DFN (2mm × 2mm) package.Output CurrentOutput VoltageLTC3025300mAAdj (0.4V to 3.6V)LTC3025-1500mAAdj (0.4V to 3.6V)LTC3025-2500mA1.2V FixedLTC3025-3500mA1.5V FixedLTC3025-4500mA1.8V FixedAPPLICATIONSLow Power Handheld DevicesLow Voltage Logic SuppliesDSP Power SuppliesCellular PhonesPortable Electronic EquipmentHandheld Medical InstrumentsPost Regulator for Switching Supply Noise Rejection
