Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
TPS7A0321PDBVR from Texas Instruments, 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 | IN | power_in | Input supply pin, accepts 1.5V to 6.0V; place 1µF or larger ceramic capacitor close to pin to minimize input impedance and ensure transient response. |
| 2 | GND | power_in | Ground reference pin; connect to board ground plane and thermal pad area for heat dissipation. |
| 3 | EN | input | Enable input with internal pull-down resistor; device enabled when voltage exceeds 1.1V, disabled below 0.3V or when floating. |
| 4 | NC | unconnected | No connection pin; internally unconnected, may be grounded or left floating. |
| 5 | OUT | power_out | Regulated output pin, 0.8V to 5.0V fixed voltage; connect minimum 1µF ceramic capacitor to ground for stability and transient response, supports up to 200mA output current. |
