RT9053AGB
Richtek Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
RT9053AGB from Richtek Tech, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Supply input, operating from 2.2V to 5.5V with an absolute maximum of 6V, and a minimum 1µF input capacitor recommended. |
| 2 | GND | power_in | Ground pin, which must be connected to the system ground plane. |
| 3 | EN | input | Active-high chip enable: the regulator is on when EN is above 1.6V and shuts down when EN falls below 0.6V (absolute maximum 6V). |
| 4 | FB | input | Output voltage feedback input, connected to the R1/R2 divider; the feedback reference is 0.8V typical. |
| 5 | VOUT | power_out | Regulator output, rated for up to 400mA with a minimum 1µF output capacitor required for stability. |
