# TPS79730MDCKREP

**Texas Instruments** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SC-70-5

TPS79730MDCKREP from Texas Instruments, in a SC-70-5. 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 | PG | output | PG is an open-drain active-high power-good output that goes high impedance when VO exceeds approximately 90% of the regulated voltage and low impedance when VO falls below approximately 90%, and it requires an external pullup resistor. |
| 2 | GND | power_in | GND is the ground terminal, and all voltage values are specified with respect to the network ground terminal. |
| 3 | NC | unconnected | NC is marked as no connection on the device. |
| 4 | IN | power_in | The IN terminal is the power supply input to the device, with an input voltage range of 1.8 V to 5.5 V for the stated output options (absolute maximum input voltage 0.3 to 6 V). |
| 5 | OUT | power_out | The OUT terminal provides the regulated output voltage of the device, with continuous output current of 0 to 10 mA, and requires an output capacitor of at least 0.47 µF between OUT and GND. |
