# TPS78236DRVT

**Texas Instruments** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · WSON-6-EP(2x2)

TPS78236DRVT from Texas Instruments, in a WSON-6-EP(2x2). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | power_out | Regulated 3.6 V output pin. Requires a small (typ. 1 uF) ceramic capacitor from OUT to GND for stability. Output current up to 150 mA; typical dropout 130 mV at 150 mA. |
| 2 | NC | unconnected | No internal connection. Leave floating or tie to ground; no functional effect on the device. |
| 3 | GND | power_in | Device ground. Both GND pins (3 and 5) must be tied to system ground for proper operation and to complete the input/output capacitor return paths. |
| 4 | EN | input | Active-high CMOS-compatible enable input. Drive above 1.2 V to turn the regulator on; drive below 0.4 V to place the device in shutdown (IGND ~ 18 nA typ). Must not be left floating. Absolute max: -0.3 V to VIN + 0.3 V. |
| 5 | GND | power_in | Device ground (second GND pin). Tie together with pin 3 and with the exposed thermal pad to the system ground plane; keep the input and output capacitor returns close with minimal impedance to this node. |
| 6 | IN | power_in | Unregulated supply input, 2.2 V to 5.5 V. Place a small 0.1 uF (typical 1.0 uF) ceramic capacitor from IN to GND close to the pin. Absolute max 6 V. |
| 7 | PAD | power_in | Exposed thermal pad on the underside of the SON-6 package. Must be soldered to the PCB ground plane for both electrical ground and thermal dissipation (RthetaJA = 65.9 C/W). |
