PMIC (Power Management IC) Voltage Regulators - Linear are commonly used in electronic circuits to stabilize the output voltage. One of the most popular voltage regulators is AP7341D-135FS4-7, which is a step-down monolithic three-terminal regulator of the low drop-out(LDO) type. This voltage regulator can produce a voltage of 1.35V by consuming a power supply voltage of 3V to 7V. Lower power version of AP7341D-135FS4-7 exists, which can produce regulated output while operating from a single-cell Li-ion battery. This voltage regulator by Diodes, Inc. (formerly Zetex Semiconductors) is a low-dropout linear regulator with a maximum output current of 1 A. It is a device intended for power supply that generates a lower-than-input voltage by using external resistors. This voltage regulator has a control pin which senses the output voltage and maintains its output voltage. The control pin is internally connected to the reference source which, in turn, provides the feedback loop action.AP7341D-135FS4-7 is typically used to generate an adjustable output voltage from an integrated 5V input supply, so that microcontrollers with an on-chip voltage regulator can operate as a stand-alone system. The use of AP7341D-135FS4-7 allows the same system to be powered from a variety of input voltages, such as 3V-7V input based on the resistor setting. The additional flexibility prevents the system from being locked into a single voltage level, even while operating on the same board.

The major features of AP7341D-135FS4-7 include its low dropout voltage (1.0V @ IOUT = 0.4A), low quiescent current (around 2mA) with good line and load regulation, power-on reset circuitry, current limit overload protection, and thermal shutdown. The AP7341D-135FS4-7 has an operating temperature range of -40\'C to +85\'C and is available in SOT-223 and SOT-89 packages.

AP7341D-135FS4-7 application field includes providing a regulated output voltage for a variety of low power applications in the fields of automotive, personal electronics, telecommunications, medical, and industrial devices. This voltage regulator is ideal for battery-operated systems, especially those powered by single-cell lithium-ion batteries. For example, AP7341D-135FS4-7 is often used with digital cameras and other image sensors to provide the regulated power supply they need to operate properly.

AP7341D-135FS4-7 offers two different methods to generate the regulated output voltage, namely, the Adjustable Output and Fixed Output. To attain the adjustable output voltage, an external resistor is required to set the desired output voltage level. On the other hand, to establish a fixed output voltage, one only needs to connect a single resistor to the control pin. Both of these methods leverage the feedback loop action described earlier.

In summary, AP7341D-135FS4-7 is a low drop-out linear voltage regulator widely used in various low power applications, from personal electronics to industrial applications. It is capable of providing a regulated output voltage from input voltages of 3V-7V with adjustable and fixed outputs. AP7341D-135FS4-7 is a reliable, stable and efficient regulator, with protection features and operating temperatures ranging to -40\'C and +85\'C.
