# TPS77601DR

**Texas Instruments** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOIC-8

TPS77601DR from Texas Instruments, in a SOIC-8. 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 | GND | power_in | Ground connection serving as the reference return for input and output stages. |
| 2 | EN | input | Negative-polarity enable (EN) input; tie to ground for normal regulator operation or drive high to place device in shutdown mode. |
| 3 | IN | power_in | Unregulated input voltage supply accepting voltage range of -0.3V to +13.5V. |
| 4 | IN | power_in | Unregulated input voltage supply accepting voltage range of -0.3V to +13.5V; may be paralleled with pin 3 for current distribution. |
| 5 | OUT | power_out | Regulated output voltage providing 1.2V to 5.5V adjustable via external feedback network; requires minimum 10µF capacitor with equivalent series resistance between 50mΩ and 1.5Ω connected to GND. |
| 6 | OUT | power_out | Regulated output voltage providing 1.2V to 5.5V adjustable via external feedback network; may be paralleled with pin 5 for current distribution. |
| 7 | FB | input | Feedback voltage input to sense output voltage and close regulation loop for adjustable versions only; requires external resistor divider with approximately 10µA divider current. |
| 8 | PG | output | Open-drain power-good (PG) output for TPS776xx devices; pulls low when regulated output voltage drops to between 92% and 98% of nominal programmed value. |
