Pinout
The TPS79501QDRBRQ1 is a high-performance, low-dropout (LDO) linear voltage regulator manufactured by Texas Instruments. It comes in an 8-pin SON (Small Outline No-lead) package. Here is a concise breakdown of its pin configuration and functions:
1. IN: Input voltage pin, where the unregulated voltage is supplied.
2. GND: Ground pin for the device.
3. EN: Enable pin; driving this pin high turns the regulator on, while driving it low turns the regulator off.
4. NR: Noise reduction pin; used with an external capacitor to reduce output noise.
5. OUT: Output voltage pin, where the regulated voltage is provided.
6. FB: Feedback pin; used to set the output voltage via an external resistor divider.
7. NC: No connection; often used for mechanical stability or spacing without an electrical function.
8. PG: Power Good output pin; indicates the status of the output voltage.
This LDO is designed for precision regulation and low noise, making it suitable for sensitive analog and RF applications.
