The LT1461CIS8-4#TRPBF is a low dropout (LDO) linear voltage regulator with an adjustable output. It is categorized as a PMIC - Voltage Reference, as it acts to maintain a regulated voltage level at its output, regardless of the load conditions present. Though the output voltage can be adjusted over a wide range, it is particularly suited to applications where stable voltages between 2V and 6V are needed. It has a dropout voltage of only 130mV (typical) when delivering 100mA from a 3.3V input, making it ideal for low-voltage, low-current regulation.
Due to its low dropout voltage, wide input voltage range, low-noise and high PSRR, the LT1461CIS8-4#TRPBF is useful for powering built-in digital circuits, direct view LED displays, efficient power converters, and other circuitry. It can also be used to power microcontroller- or DSP-intensive circuits, such as motor control systems, aircraft systems, and networking applications. The LT1461CIS8-4#TRPBF features a CMOS input stage and a P-Channel pass transistor, which provides high output current capability with low quiescent current.
The LT1461CIS8-4#TRPBF works on the principle of a simple LM317 regulator. It differs in that the output voltage is adjustable via a resistor divider and a single-pin control input, instead of the trimmer feedback adaptive design used in the LM317. The IC also includes several improved features over the LM317, such as a low dropout voltage, low-noise, high PSRR and low quiescent current.
In most applications, the LT1461CIS8-4#TRPBF is designed to be used with a resistor divider to set the output voltage. The output voltage is determined by the ratio of the two resistors, and the output voltage can be adjusted from 2V to 6V with a ±3.5% accuracy. It is important to note that increasing the load current reduces the output voltage and may cause the output voltage to go below the set voltage. To prevent this, the resistor divider must be adjusted to compensate for the load current.
The LT1461CIS8-4#TRPBF is protected against output short-circuits, and it features a thermal shutdown protection. It can also be paralleled with other regulators to increase the current output capability. Additionally, the LT1461CIS8-4#TRPBF can be used with various external components, such as bypass capacitors and series inductors, to improve the linearity and noise capabilities for a given application.
The LT1461CIS8-4#TRPBF is a versatile, sub-2V linear voltage regulator that can be used to produce a wide range of stable voltage levels. Its adjustable output voltage and wide, low-noise output range make it suitable for use in a variety of electronic systems, including microcontroller and DSP-based circuits, efficient power converters, and direct view LED displays. It is further protected against output short-circuits, and its low-dropout voltage and low-noise characteristics make it ideal for low-voltage and low-current applications.
