LT1587CM-3.45#PBF is a member of Texas Instruments\' family of fixed output, micropower low dropout linear voltage regulators that provide 3.3 V or 5 V output with a low 200 mA maximum load current. Its unique dropout voltage, low quiescent current, and low thermal resistance makes it an ideal replacement for linear and LDO regulators. The LT1587CM-3.45#PBF also features an ultralow quiescent current shutdown mode and an input overvoltage protection that prevents damage from input voltage transients. This makes the LT1587CM-3.45#PBF well-suited for applications that require a very long battery life and reliable performance in low current systems.

The LT1587CM-3.45#PBF operates from 2.7 V to 40 V input voltage and provides an output voltage of 3.45 V with a load current of up to 200 mA. The device can be powered from 1 or 2-cell alkaline, NiMH, NiCd, 1 or 2 cell Li-Ion, and other commonly used battery chemistries. It has a low dropout voltage of only 0.5 V at 10 mA output, making it an ideal choice for low voltage operation. After initial turn-on, the device requires only 18 nA of ground current with an output current up to 1 mA. It features an internal thermal limiting that provides protection against long term overloads.

The LT1587CM-3.45#PBF works on the basic principle of a voltage regulator. An integrated voltage reference providing a precision reference voltage is coupled to an error amplifier, which compares the reference voltage to the output voltage. As the output voltage deviates from the reference voltage, the error amplifier adjusts the gate drive of a power output transistor to maintain a constant output voltage. The LT1587CM-3.45#PBF also features an externally programmable output voltage. This feature allows the user to easily program the output voltage over the full range of operation, making the device suitable for powering a wide range of applications.

The LT1587CM-3.45#PBF is ideal for a wide array of PMIC applications, such as providing a regulated voltage supply, providing power to circuits in portable and embedded applications, powering systems that require low quiescent current or very low dropout voltage, and powering circuits that require stable voltage and current in input/output interfaces. The device also has a thermal shutdown mode for overload protection and can be used as a storage power supply in portable and embedded applications.

Due to its high accuracy and low voltage dropout, the LT1587CM-3.45#PBF is the perfect choice for a wide range of applications that require a low noise and accurate power supply solution. Its low quiescent current and low thermal resistance makes it an ideal replacement for linear and LDO regulators. It is also suited for powering systems that require low quiescent current or very low dropout voltage.
