LTC3025IDC#TRMPBF

LTC3025 is a micropower, VLDOTM (very low dropout) linear regulator. A BIAS supply is required to run the internal reference and LDO circuitry while output current comes directly from the input supply for high efficiency regulation. The low 0.4V internal reference voltage allows the device output to be programmed to much lower voltages than available in common LDOs (range of 0.4V to 3.6V). The output voltage is programmed via two ultrasmall SMD resistors. This device’s low quiescent current makes it an ideal choice for use in battery-powered systems. It is used in application such as low power handheld devices, low voltage logic supplies, DSP power supplies, cellular phones, portable electronic equipment, handheld medical instruments, post regulator for switching supply noise rejection etc.

• Wide input voltage range is 0.9V to 5.5V
• Stable with ceramic capacitors
• Very low dropout voltage is 45mV typical at 300mA
• ±2% voltage accuracy over temperature supply load
• Low noise is 80µVRMS typical at (10Hz to 100KHz)
• BIAS voltage range is 2.5V to 5.5V, fast transient recovery
• Shutdown disconnects load from VIN and VBIAS
• Output current limit, thermal overload protection
• VIN operating current is 4µA typical
• Operating temperature is -40°C to 125°C, package style is 6-lead plastic DFN
