Package
The UCC284DPTR-ADJ is a low-dropout linear voltage regulator with an adjustable output. It is housed in a SOP-8 (Small Outline Package with 8 pins) package, which is a surface-mount package type commonly used for integrated circuits.
Pinout
The UCC284DPTR-ADJ is a low-dropout (LDO) linear voltage regulator. It typically comes in an 8-pin SOIC (Small Outline Integrated Circuit) package. Here’s a brief overview of its pin functions:
1. IN: Input voltage supply. Connects to the unregulated input voltage.
2. GND: Ground. Common return path for the input and output voltages.
3. OUT: Regulated output voltage. This is the voltage regulated output for your circuit.
4. SENSE: Feedback pin. Connects to the output voltage for regulation.
5. ADJ: Adjustment pin. Used to set the output voltage with an external resistor network.
6. SD/SS: Shutdown/Soft-start. Provides shutdown control and soft-start functionality.
7. PG: Power Good. An open-drain output that indicates when the output voltage is valid.
8. NC: No Connection. This pin is not internally connected and can be used for routing purposes.
The UCC284DPTR-ADJ provides a simple and efficient solution for voltage regulation, especially in applications requiring a low dropout voltage and adjustable output.
