ZSR285CSTOB is a low-voltage adjustable two-terminal linear regulators, which meant to be used in small circuits to provide a regulated source of voltage. The voltage is adjustable with an external resistor, setting the current flowing through it. This voltage can be tested by a meter or other equipment to check if it follows the desired parameters. They are designed to handle up to -30 volts and .5 amperes and can be used in many applications, from battery-powered equipment to power control circuits.

The ZSR285CSTOB device is an external current-source linear regulator with an adjustable voltage output and low-noise features. It features a N-channel field-effect transistor (FET) internal power transistor, which is capable of delivering up to .5 amperes of output current. The power transistor is controlled by a voltage divider that can be adjusted by a resistor connected to the device’s pin-5.The ZSR285CSTOB is designed to be connected to a battery, to provide the power supply, or to an AC or DC supply.

The voltage regulator works by using a reference voltage (the voltage at pin 4) to control the current in the series pass transistor. A resistor generates a reference voltage between pins 1 and 4. This reference voltage, in combination with a resistor connected to pin 5, creates a voltage divider across pins 4 and 5. The voltage at pin 5 is directly proportional to the resistance of the resistor connected to pin 5, and this voltage is used to control the current into the power transistor.

The current controlled by the voltage regulator is a function of the reference voltage and the resistance connected to pin 5. When the resistance increases, the current into the transistor decreases. This current controls the output voltage, which is the potential difference between pins 3 and 2. If the voltage at pin 5 is higher than the reference voltage, the current will increase and the output voltage will rise. On the other hand, if the voltage at pin 5 is lower than the reference voltage, the current will decrease and the output voltage will decrease.

The output of the ZSR285CSTOB is adjustable between 1.2V and -30V, making it suitable for many applications such as mobile phones, digital cameras, LCD displays, power supplies, etc. The output voltage range is also adjustable by the adjustment of the resistor connected to pin 5. It has the capability to operate over a wide temperature range, from -40°C to +85°C and has a low noise and low quiescent current. It is also available in a small SOT-23 package.

The ZSR285CSTOB is a simple and economical device that is widely used in many applications. Its adjustable output voltage and low noise features make it a perfect fit for many applications, such as power management, DC-DC converters, battery-powered equipment, and automotive applications. Its compact size, low power consumption, and wide temperature range make it ideal for mobile and portable applications.
