TPNCP1529ASNT1G from TECH PUBLIC, in a SOT-23-5. 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 | EN | input | Chip Enable pin. Drive above 1.5V (VIH) to turn on the regulator; drive below 0.4V (VIL) to shut it down. Do not leave floating. EN input current typ. 1uA. Abs max -0.3V to VIN+0.3V. |
| 2 | GND | power_in | Analog ground pin. Return for input capacitor and internal analog reference; maximize PCB copper for best thermal and noise performance. |
| 3 | SW | output | Power Switch Output (LX). Switch node connecting to the external inductor; internally tied to the drains of the P-channel and N-channel MOSFET switches. Abs max -0.3V to VIN+0.3V. |
| 4 | VIN | power_in | Power Supply Input, 2.5V to 5.5V (abs max 6.5V). Must be closely decoupled to GND with a 10uF or greater X5R/X7R ceramic capacitor to minimize input ripple and loop area. |
| 5 | FB | input | Output Feedback pin. Connect to the center tap of the output resistor divider to program Vout = 0.6V * (1 + R1/R2). Internal reference VREF = 0.6V (typ, 0.588-0.612V). Abs max -0.3V to VIN+0.3V. |
