# TLV75101PDSQT

**Texas Instruments** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · WSON-10-EP(2x2)

TLV75101PDSQT from Texas Instruments, in a WSON-10-EP(2x2). 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 | FB1 | input | For the adjustable TLV75101, this pin is the control loop error amplifier input that sets the LDO output voltage (for fixed TLV751xxxyyy versions it is not connected internally). |
| 2 | GND | power_in | Ground pin. |
| 3 | EN1 | input | Enable pin for channel 1: drive EN1 above VEN1(HI) to turn the regulator on and below VEN1(LO) to put the LDO into shutdown mode. |
| 4 | GND | power_in | Ground pin. |
| 5 | EN2 | input | Enable pin for channel 2: drive EN2 above VEN2(HI) to turn the LDO on and below VEN2(LO) to put it into shutdown mode. |
| 6 | IN2 | power_in | Input pin for channel 2; use the recommended value or larger ceramic capacitor from IN to ground per the Recommended Operating Conditions table, placed as close to the device as possible. |
| 7 | FB2 | input | For the adjustable TLV75101, this pin is the control loop error amplifier input that sets the LDO output voltage (for fixed TLV751xxxyyy versions it is not connected internally). |
| 8 | OUT2 | power_out | Regulated output voltage pin for channel 2; a capacitor from OUT to ground is required for stability, with COUT between 1 µF and 220 µF per the Recommended Operating Conditions table. |
| 9 | IN1 | power_in | Input pin for channel 1; use the recommended value or larger ceramic capacitor from IN to ground per the Recommended Operating Conditions table, placed as close to the device as possible. |
| 10 | OUT1 | power_out | Regulated output voltage pin for channel 1; a capacitor from OUT to ground is required for stability, with COUT between 1 µF and 220 µF per the Recommended Operating Conditions table. |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
