LM1086IS-3.3 is an adjustable low dropout (LDO) linear regulator from Texas Instruments with a 3.3V fixed output. It is designed for use in applications requiring high accuracy, low noise, low power consumption, and fast line and load regulation. The LM1086IS-3.3 is ideal for use in battery-powered systems and in automotive applications. It features maximum output current of 1A and an on-board shutdown control circuit.

The LM1086IS-3.3 is available in the standard SOT-223, SOT-223-5 and TO-220 packages that are easily mounted on the PCB and suitable for automated production lines. With its fast transient response, good ripple rejection, and low dropout voltage, the LM1086IS-3.3 is ideal for use in a wide range of applications, including power supplies, precision circuits, digital data acquisition systems, and other sensitive electronic equipment.

The LM1086IS-3.3 is an ideal choice for high-demand applications where the output voltage must remain stable over variations in input voltage and temperature. The device provides a high power-supply rejection ratio for excellent noise performance and +/- 3% output accuracy over changes in line and load conditions.

The LM1086IS-3.3 employs a high-frequency PNP-type bias circuit together with an external compensating capacitor. To provide reliable operation, the LM1086IS-3.3 incorporates an on-chip thermal shutdown circuit and current limiting circuitry. The chip also features a low quiescent current of 30mA and a fast transient response time of 4µs.

In order to ensure optimal performance at all times, the LM1086IS-3.3 includes a range of additional safety features, such as over-current protection and short-circuit protection. The device also protects itself against reversed polarity, as a reverse biasing of the output pin is detected and the circuit is shut down.

Because of its wide range of capabilities, the LM1086IS-3.3 is ideal for use as a general-purpose low dropout regulator in applications that require low noise, low quiescent current, and fast transient response. The device is also recommended for use in point-of-load applications, precision circuits, and battery-powered systems.
