TPL720F18-5TR

3PEAK · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

TPL720F18-5TR from 3PEAK, 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 IN power_in Input voltage pin, 2.4 V to 6 V (abs max 6.5 V). Bypass IN to GND with a 1 µF or greater ceramic capacitor placed close to the pin.
2 GND power_in Ground reference pin. Connect directly to the PCB ground plane; also serves as the return path for output current and internal reference.
3 EN input Regulator enable input. Drive EN high (V_IH ≥ 1.2 V, up to V_IN) to turn on the regulator; drive EN low (V_IL ≤ 0.4 V) to shut it down. For automatic startup tie EN directly to IN. EN pin leakage is ~20 nA typ.
4 NC unconnected No internal connection. Leave floating or tie to GND on the PCB.
5 OUT power_out Regulated 1.8 V output pin, up to 400 mA. Bypass OUT to GND with a 2.2 µF or greater low-ESR ceramic capacitor for stability; an active output discharge path pulls OUT down (~190 Ω) when the regulator is disabled.
