Product Overview

The LTC3025EDC-2#TRMPBF is a 1.2V fixed output very low-dropout (VLDO) 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 device 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 and stability with ultralow ESR ceramic capacitors as small as 1µF, short-circuit and thermal overload protection and output current limiting.
  • ±2% Voltage accuracy over temperature, supply and load
  • 80µVrms Low noise (10Hz to 100kHz)
  • 2.5 to 5.5V BIAS voltage range
  • Fast transient recovery
  • Shutdown disconnects load from VIN and VBIAS
  • IIN = 4µA, IBIAS = 50µA typical Low operating current
  • IIN = 1µA, IBIAS = 0.01µA typical Low shutdown current
