The LM9076SX-3.3 is a three-terminal, positive Adjustable Voltage Regulator that provides an output voltage from 1.2 to 35V. The output voltage can be adjusted by two external resistors. It is intended for use in applications where a low quiescent current and low dropout are needed, such as personal computers. It is also suitable for general purpose applications such as distributed power system regulation, adjustable DC/DC converters and bootstrapping switches.

The LM9076SX-3.3 is a high performance monolithic PMIC Linear Voltage Regulator which is specifically designed for low voltage, low current and low cost regulation needs. It provides excellent regulation performance and low output impedance, thus eliminating the need for heat sinks. The device also features low quiescent current, low drop out voltage, and wide input and output voltage ranges, making it suitable for a wide variety of applications.

The LM9076SX-3.3 features an internal current limit circuit to protect against excessive load current, thermal shutdown with hysteresis, and self-protection from reverse battery and under-voltage conditions. This provides the durability to withstand harsh environmental conditions which is often desired in distributed power applications. The device also has low thermal resistance and high power dissipation, allowing for efficient heat dissipation.

The device also has an internal soft start/pre-bias control loop, which reduces input and output capacitor requirements, and an enable pin to enable/disable the regulator. These features enable the user to conveniently configure the device to their desired application. The enable pin is internally compensated to maintain accurate output and micro-power operation.

The LM9076SX-3.3 works on the principle of a linear voltage regulator. The working of a linear voltage regulator is based on the principle of controlling the output voltage of the regulator to a set value, by changing the input voltage to the device. In this case, the output voltage is kept constant independently of the load changes or variations in input voltage. This is achieved by using an internal feedback loop, which compares the reference voltage with the output voltage of the regulator, and adjusts the input voltage of the regulator to maintain the desired output voltage. This type of regulator is suitable for applications where the load is relatively constant and the input voltage is relatively stable, as the internal feedback loop maintains the output at the set value, regardless of changing conditions.

The LM9076SX-3.3 is an excellent choice for applications requiring low power consumption and reliable operation. With its wide input and output voltage ranges and low drop out voltage, the device can be used in a variety of applications, from low voltage post-regulation, to distributed power systems and adjustable DC/DC converters. Its low thermal resistance and high power dissipation allow for more efficient heat dissipation, and its current limit and soft start/pre-bias control loop offer convenience when configuring the device to its desired application. All these features make the LM9076SX-3.3 a perfect choice for any application requiring a PMIC Linear Voltage Regulator with high performance, reliability and convenience.
