Pinout
The RT9073A-18GQZ is a low-dropout (LDO) linear voltage regulator. It typically comes in a compact package suitable for portable and space-constrained applications. The RT9073A series is known for its high precision and low quiescent current.
The RT9073A-18GQZ specifically refers to a fixed output voltage version of the regulator, providing 1.8V output. The "GQZ" suffix typically indicates the package type, which is often a DFN-4 (Dual Flat No-leads) package, meaning it has 4 pins or leads.
The pin functions for a typical 4-pin DFN package LDO like the RT9073A-18GQZ are generally as follows:
1. VIN: Input voltage pin, where the supply voltage is applied.
2. GND: Ground pin, the common return path for both input and output.
3. VOUT: Output voltage pin, where the regulated output voltage is available.
4. EN or NC (Enable/No Connect): This pin may either be used to enable/disable the regulator or be a no-connect pin depending on specific model variations.
Always refer to the specific datasheet provided by Richtek for precise pin configuration and additional features.
